Everything works great for me, up until it gets to the Start-Process part of the scripts, then I get an error on both that say: This command cannot be run due to the error: %1 is not a valid Win32 application. Am I missing something really basic?

@Pat28K just fixed it. Needed to launch vbs file using cscript.

@mark05e Awesome, thank you for this script and for the help!
