I had a working version of GameEx Arcade on my Windows 10 dell Optiplex 960 3.49ghz with 4gb of ram. I am using MAME .220 and I have the MAME .219 romset. It was all working but with no artwork so I downloaded the MAME system pack and ran the install. All appeared to work folders are all full of media and when I first fired up GameEx it looked great but it was flickering at the bottom of the screen a little so I closed it out and tried to open the setup wizard and it wouldn’t open so I tried to uninstall and it wouldn’t uninstall so I tried to open up GameEx again and now it will not open. Shows hourglass for a second after I try to open it then nothing ever happens.
