Hi Mike, Under HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionUninstall I have just the one (ST6UNST #1)? http://forums.avsim.net/user_files/189802.jpg

Looks okay. LOL! Remove the program manually! ;-)By the way, have you done some Google searches on the issue? And I'm not sure if it has anything to do with it, but avoid installing programs to the Desktop. Use My Documents instead and ideally Program Files. Then make shortcuts on your desktop.

OK Thanks will do. Is there a way to remove the entry from the add/remove program's list?

Sometimes (not always apparently) when you try to use the "remove" function on a program which one way or another has already been removed, you will get a notice to that effect and it asks if you want to remove it from the list of installed programs.If so, then say yes obviously.There is probably a way to do it via the registry too but I do not like to mess with the registry.

Deleting the above registry key would take care of it. But as David said, Windows will usually ask if you want to remove a non-fucntioning entry.

Thanks for your help guys!
