Rollercoaster uninstallation error message HELP PLEASE !

Im having a issue uninstalling the RCT3 game due to a error when going to sand box mode i decided its not worth the time and effort. But if any help to uninstall it or send me a e-mail about it i'd be happy i tried the my computer / program files and Hit atari and deleted the files. I also attempted to do the add/remove thing to but nothing works. Any help would greatly be appreciated.

My error message :
