CCleaner 3.00.1303 x64

I installed the x64 CCleaner on my Win 7 Sp 1 installation and for the first time EVER, I have a problem.

When scanning for registry issues the new release does just fine, finding 10 or 12 unused file extensions, but when I select Fix Selected Issues CCleaner blinks but does nothing. If I re-scan all the issues are still there.

Just yesterday with one of the last releases (downloaded just a couple of days ago) everything worked just fine. I do not have any applications that are protecting my registry from modification so that would not be the issue here.

Any ideas

Win 7 SP1 isn't a general public release yet is it, it's still a beta.

May be a bit much to expect ccleaner to work with something that isn't on general release yet.
