Can't uninstall Grand Fantasia?

I went to my controle pannel and tried but I can't uninstall Grand Fantasia. When I try I get an Error pop up that says: " An error occured while trying to uninstall grand fantasia. It may have already been uninstalled. Would you like to remove grand fantasia from the programs and featured list?" But I haven't uninstalled it, and I can load it on my computer. So why can't I uninstall it? Any suggestions? It couldn't be like a virus preventing me from uninstalling it, can it? I have Kaspersky anti-virus 2011 so I think if I had something it would be quarentined or something. Help?
