No wgs, that will not work.  Go to your windows uninstall program feature and choose Proseries 2018.  Choose unistall.  It will look like you are uninstalling the entire Proseries, but then it comes up with a list to choose from to pick which states you want to uninstall.  Choose IL only because nobody likes Ilinois anyway.  Then when you open Proseries you will have to re-check IL as one of your states and do an update.  No files will be affected.
