I know this thread is old, but the script looks very viable. I am getting an error when test running the script:

I am using standalone server:

The config file is being saved to the same location as the setup.exe file

Out-Clipboard : The term 'Out-Clipboard' is not recognized as the name of a cmdlet, function, script file, or operable program.

Check the spelling of the name, or if a path was included, verify that the path is correct and try again.
