Sorry for hijacking ur thread but,
I have to admit i don't know much about the registry, but i had a look in the same place located at the top of this thread and i only got as far as " HKEY_LOCAL_MACHINE\SOFTWARE\Classes\" i do not have a folder named "CLSID".
I do not need to do anything in the registry but i thought i'd have a look to see if my entries were the same or different to other people's.
