[Scons-users] Win7 + MSVS2019 fails to create environment....

Hi Stephen,

Looking at the source code, it looks like this was fixed in 4.0.0: https://github.com/SCons/scons/blob/rel_4.0.0/SCons/Tool/MSCommon/common.py#L270

We are on scons v3.1.2 and are using MSVS2019 v16.10.2 on Win7.
When creating the win32 environment we see a dialog box saying "Windows cannot find 'powershell.exe'.", and then it fails after clicking OK:
