PSU doesn't start 32bit Powershell in Environment

PowerShell Universal

I checked a little further:

Running in custom 64bit Environment (C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe):

So the environment definitely changes something, it just doesn’t properly launch alternative powershell paths.

Starting %SystemRoot%\SysWOW64\WindowsPowerShell\v1.0\powershell.exe (by copying and pasting this in explorer) and running the same commands gives us the following outputs:

PS C:\Windows\system32> [Environment]::Is64BitProcess
False
PS C:\Windows\system32> [Diagnostics.Process]::GetCurrentProcess().Path
C:\Windows\SysWOW64\WindowsPowerShell\v1.0\powershell.exe
PS C:\Windows\system32> Write-Output $PSVersionTable.PSVersion
