Powershell script won't run file from cmd.exe with given parameters

I have the following script, and it completes all the commands EXCEPT running cmd.exe with the file/parameters given...it does not error, and it completes removing the file from the temp folder afterwards. Any idea how to get "file.exe" to run with the parameters "Location=(user-selected location code) /s" from a command line via powershell script?

Note: The following code block works fine, but is designed for a .txt file of computer names, as opposed to a GUI where the user can enter a location and computer ID individually:
