Rescue and Recovery 4.21.00.16.00 Did Not Install

[bobstockler]

I just used System Update to download and install Rescue and Recovery 4.21.00.16.00.

It told me that it did not install, but gave no reason and there were no error messages.

I tried it again and SU recognized that it was already downloaded, but the result was the

same.

Does that mean I'm stuck with 4.20.0511.00 ? ? ?

I looked into my Event Viewer and got a hint. Also, knowing that my anti-virus program,

BitDefender, has a feature that prevents modification to the registry without permission from

me, and I hadn't been asked for such, I decided to turn that feature off and try again.

That worked, and I now have the latest version of Rescue and Recovery installed.
