This game (Hellgate London) ask for HGL_x86.msi (which is located in game CD) when uninstalling.

Well, if you don’t have the CD in hand, you could just click the cancel button when it ask for HGL_x86.msi file. The uninstaller will still uninstall the game.

This is the first time I found a game which ask for game CD when uninstalling, weirdo…
