Some of my game files were damaged, so I tried repair/reinstalling the game. The problem is that the installshield is only taking a second to "uninstall". But the part of the files are still there. I tried deleating all the files manually and I also found some files hidden in the installshield folder. But my system still won't recognize the game as being uninstalled. Does anyone know a fix for this problem?
