If you are 100% certain you know the exact folder(s) where the games are,
boot the system in safe mode, delete the folders, then reboot and run
CCleaner to cleanup the leftover junk in the registry... Ben

Hi All,
I have managed to uninstall some of the games by installing them from the
Oberon Media (the game publishers) web site to repair the installation, and
then uninstalling them. Long and tedious. I have also been in touch with
Oberon on their on line help desk. They have now given up on me, and not
replied to my last message, which was sent on 11th @ 21.59 UK time. They
also don't appear to read all the message so answer the small bit which is
easy for them. All in all, they were not much use. probably because I only
want to get shot of their games. I will give up on deleting/uninstalling
the games.
Many thanks for the suggestions and help here.
Dave
