Howdy all. I have a client workstation that had a nasty bug. I was able to clean it and restore desktop etc., but every program pops up an error "Illegal operation attempted on a registry key marked for deletion". On some of the shortcuts I've been able to make it work by giving the program "start as administrator". The rest won't allow that option to be checked. Office 2010 is one of them. Anything else I can do to fix this?
