I have recently tried to download the free real player from the bbc website. It downloads without any problem, however, when I try to install it, the action is halted and I am told that I do not have administrator access to the registry. I have checked my settings and I do. This may be linked to the deletion of a trojan, but I have installed other programmes. Restore doesnn't go back far enough. Is there a simple solution or do I have to reload XP?.
