VCVARSALL.BAT for Visual studio 2017

To summarize, sth along the lines of

"C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\VC\Auxiliary\Build\vcvarsall.bat" x64

or

"C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\Common7\Tools\vsdevcmd" -arch=x64

(try running it with -help)

My environment:

** Visual Studio 2017 Developer Command Prompt v15.0.26403.7

on Win10 x64

Hans Passant is right.
I had the same problem: no VCVARSALL.BAT for my VS2017 and no Build folder in Microsoft Visual Studio\2017\Community\VC\Auxiliary. I have Visual Studio Community 2015 and 2017 installed on the same machine.
I didn't have Desktop development with C++ check in my installation. I installed it and the Build folder was created! Now everything work great.

VS2017 has reworked its directory structure and filenames. You should look for the file 'vcvars.bat', which can be located in "..\Program Files (x86)\Microsoft Visual Studio\2017\EDITION\Common7\Tools\vsdevcmd\ext\vcvars.bat" (replace EDITION with the version of Visual Studio you use).

For simplicity, you can use "%VSAPPIDDIR%" in your call to point to the IDE folder where devenv.exe is located, and go back one folder to define your path to the batch file. For example:

call "%VSAPPIDDIR%..\Tools\vsdevcmd\ext\vcvars.bat"
