I just upgraded to Visual Studio 2017 Community Edition and I have trouble loading standard header files. I get 507 errors from various header files. Here are some snippets:

I never had this issue with Visual Studio 2015 Community Edition. Am I missing some component from the Installer? Any help would be appreciated. Thank you!
C++ Solutions
Solution 1 - C++
I got the errors to go away by installing the Windows Universal CRT SDK component, which adds support for legacy Windows SDKs. You can install this using the Visual Studio Installer:
If the problem still persists, you should change the Target SDK in the Visual Studio Project : check whether the Windows SDK version is 10.0.15063.0.
In : Project -> Properties -> General -> Windows SDK Version -> select 10.0.15063.0.
Then errno.h and other standard files will be found and it will compile.
Solution 2 - C++
If the problem is not solved by above answer, check whether the Windows SDK version is 10.0.15063.0.
Project -> Properties -> General -> Windows SDK Version -> select 10.0.15063.0
After this rebuild the solution.
Solution 3 - C++
If anyone's still stuck on this, the easiest solution I found was to "Retarget Solution". In my case, the project was built of SDK 8.1, upgrading to VS2017 brought with it SDK 10.0.xxx.
To retarget solution: Project->Retarget Solution->"Select whichever SDK you have installed"->OK
From there on you can simply build/debug your solution. Hope it helps
Solution 4 - C++
I upgraded VS2017 from version 15.2 to 15.8. With version 15.8 here's what happened:
Project -> Properties -> General -> Windows SDK Version -> select 10.0.15063.0 no longer worked for me! I had to change it to 10.0.17134.0 and then everything built again. After the upgrade and without making this change, I was getting the same header file errors.
I would have submitted this as a comment on one of the other answers but I don't have enough reputation yet.
Solution 5 - C++
This problem may also happen if you have a unit test project that has a different C++ version than the project you want to test.
Example:
- EXE with C++ 17 enabled explicitly
- Unit Test with C++ version set to "Default"
Solution: change the Unit Test to C++17 as well.
Solution 6 - C++
If the instalation of Windows Universal CRT SDK as described in the acceped answer did not help. Try to check this:
In case the directory "C:\Program Files\Windows Kits" exists on your system ensure that it contains "10/Include" and "10/Lib" subdirectories. If not create hard links there to thoose present in your "C:\Program Files (x86)\Windows Kits\10"
Explanation: As you can see from C:\Program Files (x86)\Windows Kits\10\DesignTime\CommonConfiguration\Neutral\uCRT.props the path "C:\Program Files\Windows Kits" is prefered over "C:\Program Files (x86)\Windows Kits" if it exists!
