dratul....Just want to clarify something ......is the program your trying to remove part of the Win Xp system ? If its not and it doesnt show up in the list of installed programs in Control Panel ...ADD/REMOVE programs....I would do this....shut down and reboot in "Safe Mode" ......then go into "my computer " C drive /programs folder ......it should be there ......assuming it is ...high-light the folder and select delete ......if it wont let you do that...open the folder and delete the items one at a time until they are all gone . Then reboot back into normal mode . Then I would go to the registry and do a search for that program name and remove it .
If you have a good registry cleaner use it instead of manually removing .
Be sure to make a backup of your registry just in case .
let us know how you make out
