This is getting more interesting. I rechecked 'programs and features' and the item does not appear there. Yet it is in Programs and on the desktop as an icon.
Clicking on either, then trying to un-install, using the programs own un-installer, I get messages to complete the installation, and then suggestions 'Windows items are missing'. I am then unable to proceed further.
I have just made further attempts at removing the program, using some of the advice given in rdave13 link. The computer as CCleaner, and this was a way suggested to try, but alas the program ins't in the CCleaner uninstall section. I also note from the link that someone else was having similar problems with an awkward set-up.
Problem I now seem to face, is there are downloads within the link, that I am unable to try or use at the moment!.
Any other suggestions or ideas still very welcomed.
You could try reinstalling it from the disc again. First I'd run Ccleaner's registry cleaner.
Press shift after inserting the disc to stop it auto playing. Go to computer and open the disc. See if you can find the installer file. Right click and select 'run as administrator'. Hopefully it will install. Now go to programs and features to see if listed now. That's the only thing I can think of.
