Remove and reinstall steps.
If you still have the installer for the version of the GPMC extension that is on that machine there is a way to remove it. Take the old installer msi for the GPMC extension only and run it on that machine. It should give you the option to uninstall the GPMC extension. If not, it should allow you to install the same version, as the version being installed will match the version on the machine, and then that should let you uninstall the extension.
