VS2015 cl Can't find CRT libs (stdio.h, ctype.h etc.) when building on command line

Question

• I have installed the latest VS2015 Professional version.
• Opened the Visual Studio command prompt and ran vcvars32.bat
• wrote a simple helloworld.cpp p

Answer 1

I ran into a similar problem on VS2017 (15.5.5) when building VC++ projects against Windows SDK 8.1:

C1083 Cannot open include file: 'assert.h': No such file or directory

Checking Windows 8.1 SDK and UCRT SDK in the VS installer solved the problem.
