Running Vista basic 64 bit, service pack 2.. have used the verification tool to verify all the dot net frameworks from 1.1 to 3.5.. passed
used the clean up utility to remove framework 4.. it says it was successful but appears to still be there..i.e. i can 'remove' framework 4 five times in a row (!)
It appears that the record of 'failed' windows update attempts for .net4 go back all the way to febuary.. so it's not anything recent..
The error is code 643, which would (IIRC) imply that i have not got all the service packs installed, but I do, and unlike the way it used to be, you can't re-install a service pack without uninstalling it first..
Since I am concerned that the bug that won't allow installation of .net 4 would manifest some othewr unexpected place if i tried reinstalling a sevice pack, i don't want to go the uninsstall/reinstall route unless i *really* have to...
Frankly i'm at a loss..
