But one way you can get rid of the game itself is to locate to My Programs or wherever it be that you saved hitman when installing it and try to find an icon named uninstall, or the setup file that instaals/repairs/uninstalls the game from your hard disk. If not you could delete those files. Incase you need it back I would leave it in the recycle bin.
hope this helps, jake

Rather than delete the referenced files, just rename the folder.
Example, if the folder is called ABC, rename it ZABC.
That way if you need to bring it back, all you have to do is rename ZABC to ABC.
Much easier and safer since some Recycle Bins purge after 24 hours or less.
Depending on how important this is, there are products on the market that reportedly will do what you want. Here is one. Check it out -
