I have Need for Speed game installed on my pc, But i want to remove it as i dont play it any more, now the problem is that i do not find an uninstaller for the game, neither does it show in add or remove programmes , i tried Revo uninstaller, but it doesn't show up there as well,I dont have the access to the intallation cd, how can i remove it?

It sounds like your only option is to delete the folder it is located in. Then delete any shortcuts in your Start menu or desktop. This will not remove any entries in your Registry, but that should not hurt anything.
