Un/installing GP3 Problems - Windows 10

I installed GP3 but wasn't concentrating on the location. So decided to uninstall to re install.

Unfortunately, GP3 still remains in the list of installed apps in W10 Settings. Running uninstall doesn't remove it.

I have used CCleaner to remove orphan registry entries etc and deleted any files and folders I can find.

I've tried to install GP3 from CD and HDD, but on the initial screen splash there is only an uninstall option. And the play option doesn't work.

Wondered if there are any other ideas??

Solved. It was an orphan directory in C:\Program Files (x86)\Installshield Installation Information. Revo Uninstall dealt with it and able to reinstall GP3.
