Can't uninstall Fallout 3 Game of the Year Edition

I want to uninstall this game but it's not working. I went to "uninstall a program" and found fallout 3 and tried to uninstall it but it didn't work. An error message came up and wouldn't let me uninstall it.

I put the disk in and tried to get to setup but I don't see it. What do I do?

I'm on windows 7.

Sorry for being a noob. And thanks.
