Comments:

'sudo' is my little function that submits its args to Start-Process with the addition of -Wait and -Verb RunAs options.
So, we wind up with 'msiexec' being the -FilePath value, and the rest being the -ArgumentList value.

'msiexec' actually doesn't take the "normal" simple list of arguments, but rather "/i foo.msi" or "/f foo.msi" has to be
one argument.
