i have managed to reinstall GSX finally but the problem with the GSX configurator persists
did you read the thread?
You mixed up a lot of issues in the same thread, like your issues with the Addon Manager, the message about the antivirus, the "script not started", has ALL of these being solved, meaning you don't have any errors at start ?
If yes, then why even discussing these issues ? The thread I linked was obviously to help you solving THESE issues and THESE issue only, once you clarify if you fix them, we might discuss your "configurator" issue AFTER you would explain it clearly.
But I first need to know if your installation has completed correctly.
