Visual studio windows universal crt sdk

March 3rd, 2015

In June of last year we published a pair of articles discussing the major changes that we had made to the Visual C++ C Runtime (CRT) for Visual Studio 2015. In “The Great C Runtime (CRT) Refactoring” we explained the major architectural changes that we had made to the CRT. In “C Runtime (CRT) Features, Fixes, and Breaking Changes in Visual Studio 14 CTP1” we enumerated all of the notable features we’d implemented and behavioral changes that we’d made.

We’ve received a lot of feedback from you, our customers, over the months since we wrote those articles and released the first Community Technology Preview (CTP) of Visual Studio 2015. We are especially appreciative about the many excellent bugs that you’ve reported on Microsoft Connect. While we haven’t made many changes to the CRT since that first CTP, we have indeed been hard at work on addressing your feedback, working on further improvements, and finishing up some longer-running projects. The recently-released Visual Studio 2015 CTP6 has all of these improvements that we’ve been working on. We’ll be discussing these changes in a pair of articles again: this article discusses the major architectural changes since the first CTP; a subsequent article will enumerate all of the new features, bug fixes, and breaking changes in greater detail.

In our articles last June, we explained how we had split the CRT into two logical parts: The VCRuntime, which contained the compiler support functionality required for things like process startup and exception handling, and a “stable” part that contained all of the purely library parts of the CRT, which we would service in-place in the future rather than releasing newly versioned DLLs with each major version of Visual Studio. At the time, this “stable” part took the form of two libraries: the AppCRT and the DesktopCRT (the release DLLs were named appcrt140.dll and desktopcrt140.dll).

The VCRuntime still exists in the same form and with equivalent contents as in previous CTPs. It’s in the “stable” part that we’ve made major changes in this latest CTP6. The AppCRT and DesktopCRT have been recombined into a single library, which we have named the Universal CRT. The new DLLs are named ucrtbase.dll (release) and ucrtbased.dll (debug); they do not include a version number because we’ll be servicing them in-place.

The Universal CRT is a component of the Windows operating system. It is included as a part of Windows 10, starting with the January Technical Preview, and it is available for older versions of the operating system via Windows Update.

Building Software using the Universal CRT

Previously, all of the CRT headers, sources, and libraries were distributed as part of the Visual C++ SDK, installed in the VC subdirectory of your Visual Studio installation (generally C:Program Files (x86)Microsoft Visual Studio 14.0VC). The files for the VCRuntime are still part of the Visual C++ SDK. The headers, sources, and libraries are now distributed as part of a separate Universal CRT SDK. This SDK is included with Visual Studio; it is installed by default to C:Program Files (x86)Windows Kits10. The debug ucrtbased.dll is also included as part of this SDK and is installed to the system directory.

We have updated the Visual C++ MSBuild props and targets files to add the new Universal CRT directories to the include and library paths. If you create a new project in Visual Studio 2015 or upgrade an existing project to Visual Studio 2015, it should generally pick up these new directories automatically. If you upgrade a project that does not use the Visual C++ MSBuild props and targets files or that does not inherit the default include and library paths from those props and targets files, you’ll need to update your project manually to include the new directories. You can use the following MSBuild properties to find the Universal CRT SDK files:

    $(UniversalCRT_IncludePath)
    $(UniversalCRT_LibraryPath_x86)
    $(UniversalCRT_LibraryPath_x64)
    $(UniversalCRT_LibraryPath_arm)

So long as you do not link with the /nodefaultlib option, all of the correct library files will be found when you link your project. If you link with the /nodefaultlib option, you will need to link several extra libraries when you link. For example, whereas you previously might have just linked msvcrt.lib in order to use the CRT DLL, you will now also need to link vcruntime.lib and ucrt.lib. Here is a table that shows which libraries you will need to link for each “flavor” of the libraries:

    Release DLLs   (/MD ): msvcrt.lib   vcruntime.lib      ucrt.lib
    Debug DLLs     (/MDd): msvcrtd.lib  vcruntimed.lib     ucrtd.lib
    Release Static (/MT ): libcmt.lib   libvcruntime.lib   libucrt.lib
    Debug Static   (/MTd): libcmtd.lib  libvcruntimed.lib  libucrtd.lib

Distributing Software that uses the Universal CRT

In the past, you might have used one of the many ways described in “Deployment in Visual C++” to redistribute the Visual C++ libraries along with your software. For all Visual C++ libraries except the Universal CRT, there is no change in the way deployment can be done. Whatever mode of deployment (central, local or static linking) was used earlier can still be used.

However, with the above mentioned change to move the Universal CRT into the Windows Operating System, there are a few note-worthy changes:

1. The Universal CRT is a Windows operating system component. It is a part of Windows 10. For Windows versions prior to Windows 10, the Universal CRT is distributed via Windows Update. There are Windows Update MSU packages for Windows Vista through Windows 8.1. Currently these MSU packages are installed as part of the VCRedist installation. In a future build of Visual Studio 2015, these MSU packages will also be distributed separately as part of the Universal CRT SDK and made available for download on support.microsoft.com.

2. If you build software designed for use on Windows operating systems where the Universal CRT is not guaranteed to be installed (i.e., Windows 8.1 and below), your software will need to depend on the above mentioned Windows Update packages to install the Universal CRT.

3. If you currently use the VCRedist (our redistributable package files), then things will just work for you as they did before. The Visual Studio 2015 VCRedist package includes the above mentioned Windows Update packages, so simply installing the VCRedist will install both the Visual C++ libraries and the Universal CRT. This is our recommended deployment mechanism. On Windows XP, for which there is no Universal CRT Windows Update MSU, the VCRedist will deploy the Universal CRT itself.

4. If you currently statically link the Visual C++ libraries, then things will continue to work just as they currently work for you.  We strongly recommend against static linking of the Visual C++ libraries, for both performance and serviceability reasons, but we recognize that there are some use cases that require static libraries and we will continue to support the static libraries for those reasons.

5. There will not be a merge module for the Universal CRT. If you currently use the CRT merge modules and still want to deploy the Visual C++ libraries centrally, we recommend that you move to the above mentioned Windows Update package or to the VCRedist. Alternatively, you may choose to link statically to the Universal CRT and the Visual C++ libraries.

6. Updated September 11, 2015:  App-local deployment of the Universal CRT is supported.  To obtain the binaries for app-local deployment, install the Windows Software Development Kit (SDK) for Windows 10.  The binaries will be installed to C:Program Files (x86)Windows Kits10Redistucrt.  You will need to copy all of the DLLs with your app (note that the set of DLLs are necessary is different on different versions of Windows, so you must include all of the DLLs in order for your program to run on all supported versions of Windows).  App-local deployment of the Universal CRT is not supported. The Universal CRT is a Windows operating system component. Eventually (long-term), the Universal CRT will always be present on every machine, just like other operating system components today. We realize that there are today existing operating system versions where this component is not present, and we recognize that you, our customers will need to support these operating systems for some time. We hope that using the Windows Update package or static linking will suffice. One of the primary goals in our effort to refactor the CRT for this release was to mitigate the runtime proliferation problem, where over time computers end up with a large number of copies of the runtime libraries.

As we mentioned previously, we’ve made many bug fixes and other improvements to the CRT since we introduced the refactored CRT last June in CTP1. Later this week we’ll have a second article that discusses these changes in greater detail. In the meantime, we’re very interested in your feedback about the new Universal CRT.

Visual C++ Libraries

I’ve just installed Visual Studio 2015 on my working laptop with Windows 10.

I’ve cloned a repository with a solution created with the same version of Visual Studio (update 3) on another PC, always with windows 10.

When I try to build the solution on my laptop I obtain the following error:

c:program files (x86)microsoft visual studio 14.0vcincludecrtdefs.h(10): fatal error C1083: Cannot open include file: 'corecrt.h': No such file or directory

In this page I’ve read that I must add $(UniversalCRT_IncludePath) to my include paths, but even in this case I obtain the same error.

I’ve checked and $(UniversalCRT_IncludePath) refers to this path:

C:Program Files (x86)Windows Kits10Include10.0.10240.0ucrt

This path is missing on my laptop. Instead I’ve this one:

C:Program Files (x86)Windows Kits10Include10.0.10150.0ucrt

So it seems that window version is different. Probably this is true, because on my laptop I didn’t installed the 1511 windows updgrade, while in the other pc is all installed correctly.

My question is how can I refer to corecrt.h file in both pc without make a mess with paths. I’d like to avoid to hard-link these path because they are pc dependent. and I don’t understand why in my laptop the path is wrong considering that it should be system dependent and not cabled into solution.

How can I solve this issue? I know that I can update my laptop to the same windows version but I’d like to avoid it for many reasons.

— EDIT

I’ve noticed that that I have this path:

C:Program Files (x86)Windows Kits8.1Include10.0.10240.0ucrt

It has the same 10.0.10240.0 version but related to another windows kit version, so maybe there’s some problem in this case. On my laptop I’ve also Visual Studio 2013, so maybe it can came from it, but I cannot remove it because I’m maintaining another project with Visual Studio 2013 and I cannot remove it yet.

Maybe in Visual Studio 2015 folder I can set explicitly the $(UniversalCRT_IncludePath) in some .bat file (vcvarsall.bat or similiar) but I don’t know which file and in which position.

Some Windows PC users who tried to install or run new and current desktop apps (for example, Creative Cloud or other software) came across the new system error about missing api-ms-win-crt-runtime-11-1-0.dll file.

Do you also have problems with running some newer applications on your older Windows 8.1, 8, 7 and other versions? You might need to get one update in order to fix possible problems with running Windows 10 desktop apps on your computer with older operating system version. A number of modern tools depends on Windows 10 Universal C Runtime and unless you install the important update, you won’t be able to enjoy CRT programs.

We have already told you how to remove iPhone activation lock so now let’s learn more about CRT and share direct links where you can download the update for Universal C Runtime and solve the future problems and bugs or current issues you experience with your desktop machine and some applications.

Universal C Runtime in Windows

What is Universal CRT? This is one of the many components in Windows OS. What does it do for end users? Windows CRT Runtime is responsible for CRT functionality. In other words, it can enable such functions on different Windows computers. When you install this upgrade you’ll be able to run Windows 10 Universal C Runtime dependable applications on earlier platforms such as Windows 8.1, Windows 8, 7 etc.

A lot of desktop applications built via Windows 10 SDK depend on the Universal C Runtime. This has happened ever since Microsoft Visual Studio 2015, and users who want to launch programs built with the latest Software Development KIT (SDK) have to install the additional CRT element. This way all your apps would work correctly.

Windows Runtime Component: Supported Systems

Not all operating system versions require the update api-ms-win-crt-runtime-11-1-0.dll. So who really needs it?

All users who are still running Windows 8 or even older Windows 7 SP1 are advised to install the new element. Those computer owners who have previous Windows 8.1 or Windows RT 8.1 are also advised to follow the links. The regular Windows RT version also needs an update as well as Windows Server 2012 (and 2012 R2) and Windows Server 2008 (both SP1 and SP2).

What about Vista version? If you are using Windows Vista SP2 you should also use the upgrade.

How to Download Universal C Runtime

Are there any requirements you have to meet in order to update and use all apps without issues? Actually, some prerequisites do exist. For example, if you are running Windows 8.1, RT 8.1 or Server 2012 R2 version you must have installed the update released in april 2014. If you have Windows 7 version or Server 2008 R2 software you are required to install Service Pack 1. Vista and Server 2008 users should download and install Service Pack 2.

There are two main ways how to download and install updates for Windows PC. One is via your Update center. The other one is through the official download center. Let’s discuss each one and explain in details how you can follow it.

Get Universal C Runtime through Windows Update

Step 1. Select the Start Menu and choose All Programs (or go to Control Panel – System and Security).

Step 2. Choose Windows Update.

Step 3. Select Get updates.

Step 4. Now choose Check for updates menu.

Step 5. Your computer will check for all available files and show you the list.

Step 6. Select Universal C Runtime and click on Install Update. Or just press on Install Updates to make sure all new files (including api-ms-win-crt-runtime-11-1-0.dll) are downloaded and successfully installed by your personal computer.

By the way, this is the only method that works for Windows RT and RT 8.1 since there is no direct link for the supported file for these two system versions.

CRT Download Links

Step 1. Most extensions and files offered for Windows PC are self-extracting .exe files. You are advised to download the file to the blank disk or your hard drive.

Step 2. Create a new folder to save the file. Do not save it to your Windows folder directly by yourself to avoid any unknown bugs and problems (the extension can overwrite your existing files and cause various issues afterwards).

Step 3. Use the direct link from the official Microsoft Download Center for your particular system to get the support file to improve app performance:

• Windows 8.1 x64
• Windows 8.1 x86
• Windows Server 2012 R2 x64
• Windows 8 x86
• Windows 8 x64
• Windows Server 2012 x64
• Windows 7 x86
• Windows 7 x64
• Windows Server 2008 R2
• Windows Vista x64
• Windows Vista x86
• Windows Server 2008 x64
• Windows Server 2008 x86

According to Microsoft, all these files and links have been scanned for viruses and are safe to get and use on your PC. Besides, the updates are stored on the secured servers so no third-party changes can be added to them.

Step 4. Open the file and it will be installed on your computer right away.

P.S. When you install the CRT update there is no need to add any changes to the registry [the file itself also doesn’t replace any previous updates you installed earlier]. However after the file is successfully installed it will be better to restart your computer. This way the update will be applied at once and you’ll successfully run any apps dependable on Windows 10 Universal C Runtime.

Google Test framework is provided with a solution already generated that we can use with Visual Studio.

It’s the gtest.sln file.

But to use it we have to accomplish some steps in order to having it working properly.

This is what we will see in this Google Test tutorial.

Let’s get started.

First of all

For this tutorial we need:

• Visual Studio 2017 Community: https://www.visualstudio.com/downloads/
• Google Test 1.8.0: https://github.com/google/googletest/releases

Google Test will be installed in this directory:

• C:devc++mylibgoogletest-release-1.8.0

Using files for Visual Studio

We are going to use the files generated directly by Google for Visual Studio, they are in this directory:

• C:devc++mylibgoogletest-release-1.8.0googletestmsvc

You can see gtest.sln, double-click it to open the solution in your IDE.

You will be invited to One-way upgrade all your files, click OK.

But when you try to Rebuild Solution, you’ll see the following error:

Severity Code Description Project File Line Suppression State

Error MSB8036 The Windows SDK version 8.1 was not found. Install the required version of Windows SDK or change the SDK version in the project property pages or by right-clicking the solution and selecting "Retarget solution". gtest_main C:Program Files (x86)Microsoft Visual Studio2017CommunityCommon7IDEVCVCTargetsPlatformsWin32PlatformToolsetsv141Toolset.targets 34 

Don’t worry, there is a way to fix it.

Indeed we have to install 2 components:

• Windows 8.1 SDK
• Windows Universal CRT SDK

You have to run the vs_community.XXXXX.XXXXX.exe launcher (the one you use to install Visual Studio), you’ll have the choice to Modify your Visual Studio Community 2017 IDE.

Or just simply do from Visual Studio > Tools > Get Tools and Features…

Click Modify.

You should have already installed the Desktop development with C++ components.

It’s logically already checked.

Then, from the top of the launcher, you have 3 tabs:

• Workloads
• Individual components
• Language packs

Select the Individual components tab.

OF COURSE, REALLY IMPORTANT: close all instances of Visual Studio before proceeding.

Otherwise, you won’t be able to modify the installation.

From the list, at the end, you’ll see the Windows 8.1 SDK (from the SDKs, libraries and frameworks part).

Its size is 298 MB.

Then we need another component, this time from the Compilers, build tools and runtimes part:

Select Windows Universal CRT SDK (this is the C RunTime which fixes some bugs).

Its size is 312 MB.

So for both components we have Install size: 610 MB.

Click Modify, just below, to install them.

The new installation is starting.

Wait until everything is installed and click Launch.

OK let’s back to Visual Studio.

Generating the gtest.lib or gtestd.lib

Reopen the gtest.sln solution.

Then on the Solution Explorer, right click the Solution ‘gtest’ > Retarget solution > Select 8.1 from the Windows SDK Version combobox > OK.

Then Rebuild Solution.

This time, everything should be OK.

Depending if you built your solution in debug or release mode, you have now two new files:

• C:devc++mylibgoogletest-release-1.8.0googletestmsvcgtestDebuggtestd.lib
• C:devc++mylibgoogletest-release-1.8.0googletestmsvcgtestReleasegtest.lib

It’s important to note that for the debug output there is a «d» letter in gtestd.lib.

Generating the library was really important because it was the main purpose of this tutorial.

Running tests

There are two ways to run the tests, either with a CLI or with an adapter directly from Visual Studio.

With a command-line interface (CLI)

It’s possible to launch the tests directly from a CLI such as Cygwin, PowerShell or the old cmd.

So as we’ve just building our gtest projects, we can now check that some executables have been created, you can see them in the following directory:

• C:devc++mylibgoogletest-release-1.8.0googletestmsvcgtestDebug

So open your CLI in this directory and just type for example:

./gtest_prod_test.exe

The result:

Running main() from gtest_main.cc
[==========] Running 2 tests from 2 test cases.
[----------] Global test environment set-up.
[----------] 1 test from PrivateCodeTest
[ RUN      ] PrivateCodeTest.CanAccessPrivateMembers
[       OK ] PrivateCodeTest.CanAccessPrivateMembers (0 ms)
[----------] 1 test from PrivateCodeTest (1 ms total)

[----------] 1 test from PrivateCodeFixtureTest
[ RUN      ] PrivateCodeFixtureTest.CanAccessPrivateMembers
[       OK ] PrivateCodeFixtureTest.CanAccessPrivateMembers (0 ms)
[----------] 1 test from PrivateCodeFixtureTest (1 ms total)

[----------] Global test environment tear-down
[==========] 2 tests from 2 test cases ran. (3 ms total)
[  PASSED  ] 2 tests.

You can do the same with the gtest_unittest.exe file but result will be much longer.

With an adapter

This adapter is the Google Test Adapter.

It’s not an official tool from Google, but it will help us to discover all available tests from the Google Test framework.

It’s essential because without it, we won’t be able to see them.

So from Visual Studio > Tools > Extensions and Updates… > On the left, click the Online section > Then on the right type Google Test Adapter in the search input.

The current version is 0.10.1.793, it adds support for the C++ unit testing framework Google Test.

Install it and close your Visual Studio, the extension might take many minutes to setup by VSIX.

Once done, reopen Visual Studio then > Test > Windows > Test Explorer.

You can see all tests discovered by the adapter.

To run them, just click Run All (in blue) above tests.

At the end of the run, you should have 433 tests: 421 passed and 13 skipped.

If yes, congratulations, you have just finished this tutorial.

Possible error with the Adapter

The 'GoogleTestExtensionOptionsPage' package did not load correctly. 

The problem may have been caused by a configuration change or by the installation of another extension. You can get more information by examining the file 'C:UsersUsernameAppDataRoamingMicrosoftVisualStudioVersionNumberActivityLog.xml'. 

Restarting Visual Studio could help resolve this issue. 

Continue to show this error message?

This error is due to the fact that you already installed a version of Google Test Adapter.

Maybe not exactly the same, there are indeed 2 different versions:

• Test Adapter for Google Test
• Google Test Adapter

They are the same except that the latter is up to date.

Conclusion

You are now ready to implement your own tests and check their results directly from Visual Studio.

Good job, once again, you did it.

Api-ms-win-crt-runtime-l1-1-0.dll отсутствует: как исправить

Ошибка «Запуск программы невозможен, так как на компьютере отсутствует api-ms-win-crt-runtime-l1-1-0.dll. Попробуйте переустановить программу» возникает при попытке запустить на Windows 7 или 8 приложение, предназначенное специально для Windows 10. Второй вариант — в Windows не установлена или некорректно работает среда выполнения C++ — Microsoft Visual C++ 2015. Нужно установить обновление.

Решить проблему можно тремя способами:

Исправление ошибки api-ms-win-crt-runtime-l1-1-0.dll

При установке новой программы на Windows 7/8 может появляться системная ошибка «Запуск программы невозможен, так как на компьютере отсутствует api-ms-win-crt-runtime-l1-1-0.dll. Попробуйте переустановить программу». Чаще всего, с указанной динамической библиотекой все в порядке, просто софт разрабатывался для «Универсальной среды выполнения C» (CRT) с учетом новых функций Windows 10.

Нужно обновить среду выполнения C++. Это также актуально при ошибке с «отсутствием» api-ms-win-crt-runtime-l1-2-0.dll или других динамических библиотек Microsoft Visual C++.

В первую очередь нужно проверить, нет ли сбоя:

Обновление среды выполнения C++:

Если установка MV C++ 2015 не удается или выполняется некорректно, можно сразу поставить обновление системы KB2999226. Это обновление содержит необходимые динамические библиотеки и подходит для Windows 7/8/Vista/Server 2003 и других версий системы.

Информация с сайта Microsoft:

Microsoft Visual Studio 2015 создает зависимость от универсальных CRT при построении приложений с помощью Windows 10 Software Development Kit (SDK). Это обновление можно установить на более ранние операционные системы Windows, для правильной работы этих приложений.

Для Windows 7 загрузка обновления KB2999226 доступна по прямой ссылке — https://www.microsoft.com/ru-RU/download/details.aspx?id=49077.
