Unfortunately, I need to install software with custom parameters and the installation is only possible with the prompt, so PowerShell only serves me as a bridge.
That said, if you want to remove the need for the CMD all-together, post its contents here and I’ll try to convert it to PS.
I had a tonne of issues getting parameters to work in PS when I started. There was a utility I used that showed how PowerShell would see the parameters given to it. Maybe you can still find it.
