Dear Guys,
I owned a game called Batman: Arkham Asylum on Windows XP. Its not about the game. Thing is, the game didn't work and I did a serious blunder. I deleted the game INSTEAD of uninstalling it. And Add or Remove Programs, that silly FOOL, thinks it's still on the computer. Later, when I got the working version of the game, the PC prevented me from installing it as according to it, it was already on the computer. I try to uninstall it, and it says that its files are missing. Like, duh!
Please, help me get this game back as it is really awesome (and costly too ).If you have another computer or can use a friend's computer, you could try installing it on that computer (doesn't have to be able to run it). Copy the installation onto a DVD or external drive, then copy those files to the location they should be at on your computer and then uninstall it from both computers.

Delete it from registry
