Trying to use Execute-Process to run dpinst - crashes

I’m trying to duplicate the following using Execute-Process:

& “$PathtoDpinst\dpinst.exe” /path ‘c:\program files\folder\driver files’

I tried all kinds of different permutations, but can’t get it work work.
e.q. Execute-Process -Path “$PathToDpinst\dpinst.exe” -Parameters "/path ‘c:\program files\folder\driver files’

All I seem to get with Execute-Process is the dpinst help window and a powershell crash. DPInst keeps reporting that it can’t find the path (c:\Program;-). I tried ’ around the path. I tried `" instead. Nothing seems to work.

-Parameters "/path `'c:\program files\folder\driver files`'"
