I went on line to ask about dll problems. One that sounded interesting was Registrypatrol that can fix all your problems. I went through a rather long process to get my 'unlock code.' Tried many times to access the site and it never happened. Emailed the technical support site http://patrolsoftware.com/technicalsupport.html. Was told that it would take 1 to 2 days to get back to me. This has been over a week. My last email to them was to say that I would file a dispute with my bank. No response from that. Do Not Go There !!!
