Finally had to learn to overcome the "Access Denied" registry key problem, also known as the "error 0x80070005" problem. This comes up most often when trying to uninstall AVG Antivirus, but also on other occasions.

I knew there was a guy out there somewhere who knew how to do it and had clear instructions. The problem is, as usual, the Internet is flooded with thousands of blog entries by the totally clueless trying to be helpful, and a zillion crooks trying to get you to pay $34 for a "registry repair" solution that probably doesn't actually do anything worthwhile.

I had the tool I figured I'd need - Microsoft's command line subinacl tool, but it's manual is so long and cryptic I considered figuring out how to use it from there a last resort.

Fortunately I did, after a few hours of searching, find the guy with the answer - all of 5 lines of instruction.

He did, however, omit the final step. Once you can actually get in and view the advanced properties, you'll find one or more permission lines saying "Deny Everyone" and you need to delete those.

. . I have to reformat my instructions into html before I can actually post it - not many can read Papyrus format (but they should - Papyrus is the best and fastest word processor / light publisher on the face of the Earth).
