Just to be clear. ??? Should WebRep be doing anything as of right now on my IE9 RC1 32 bit browser? Just let AvastFree upgrade to 6.0.1000 and was asked to agree to WebRep. It appears in my Manage Add-ons list but the toolbar is dead and Vast’s GUI reports it isn’t installed but gives an error if i click to install it. See image: Don’t want to uninstall/reinstall if it’s a snafu at other end. 
Cheers
Try a repair of avast first then see if you are able to install webrep.
Used the uninstall exes in safe mode and reinstalled 6. All’s well with WebRep ;D Comodo’s Defense+ might have blocked some registry changes last time. Turned that off too. Easy when you do it right :
Now need to find out if Avast will fight with Comodo’s sandbox. Life’s full of challenges. Great upgrade tho. 8)
Cheers
Glad its working
