Hi Peter,
Thank you for your input. I was able to run Start-Process C:\Folder\SomeProgram.exe -ArgumentList /s -Wait directly without any prompts and everything installs just as I expected. My issue is with the Invoke-Command.
I will give option 3 a try: My installer has a SQL Express 2012 and an .msi in it… at this point I’m willing to try anything
