I'm not sure about vista,but this is the way it installed on XP,click on start then click computer,then click on the C: drive and look for a folder named GAMES,click on GAMES folder,if its there then just delete it.
The last couple of games from GAOTD have not come with uninstall options,and they are not installed in the programs folder.If the above did not do it, then try doing a search,using the game name in the search box and delete the files that way.
Heres the same thing stated another way by another member.
"Some downloads, like this one, will automatically install to C:\Games\ (it shows that it's doing that in the install pop up AND tells you that in the README)
NOT in Documents, in C:\Games\ .... unless you SPECIFICALLY change the path to a preferred location which you can do using the BROWSE button on the popup."
Hope this helps,if not post your outcome and someone will be along to help.
