Sorry if this looks more like a support request.  There's probably something wrong in my setup (I do have Visual Studio 2015 installed, though).

I am trying to build on Windows using "Tools\buildbot\build.bat -p x64".  It worked a few months ago.  Now I get:

Build FAILED.

I changed the default Windows SDK version at some point, because it was falling back to v8.1 and we really ought to use v10. It auto-detects all the v10 versions, so I'm guessing you haven't got any of them installed right now.

The dev guide just says to install VS 2017, which will include it. We should probably have manual install steps listed somewhere as well, though I'm hesitant to make the "getting started" steps too complex. And I've already switched 3.7 to use the v141 toolset, which is in VS 2017 but not VS 2015 (but it's binary compatible with the older v140, so shouldn't matter).

For VS 2015, you can get the Windows 10 SDK from https://developer.microsoft.com/windows/downloads/windows-10-sdk (only the headers and libraries option is required).

Thank you.  Though now I get the following issue:

       "c:\t\cpython\PCbuild\pcbuild.proj" (Build target) (1) ->
       "c:\t\cpython\PCbuild\pythoncore.vcxproj" (Build target) (2) ->

Strange, that should have been installed.

Do you see rc.exe anywhere in "C:\Program Files (x86)\Windows Kits\10"? If not, might need to repair the SDK you just installed. It shouldn't be a separate option from anything else in there.

Yes, it's in "C:\Program Files (x86)\Windows Kits\10\bin\10.0.16299.0\x64"

Is there one in x86 as well? Perhaps it isn't finding x64 tools properly (I've seen this once or twice in the past with VS 2015, but I think it was fixed at some point)

Yes, both in x86 and x64. And `tools\buildbot\build.bat` fails regardless of whether I pass `-p x64` or not.

It shouldn't be any different, but what about PCBuild/build.bat?

Yes, same thing.

Are you using a normal command prompt or the Visual Studio one? Totally clean environment should work fine these days, but I suspect there's an environment variable affecting something.

"set" to show everything that is set, remove any personal info and post or just email it to me if you'd like me to check.

It's a normal command prompt.  Here is the output of "set":

Ok, I've decided to bite the bullet.  I uninstalled VS 2015 and installed VS 2017 Community Edition.  Things seem to work now.  Thanks for the help!
