Generally on the .net frameworkhttp://www.bleepingcomputer.com/forums/t/264765/security-update-kb953297-fails/
FYI - I have the following:
Version 3.5 SP1
Version 1.1 does not seem to be necessary and when it is offered
as an update, if it will not install, you can select 'Don't show this update again'.
No program has called for the 1.1 version; until that happens, I regard it as unnecessary.
What versions do you have? Check Add /Remove.
To get to 3.5 SP1:
Uninstall other versions first.
cumulative update for .net framework 3.5 SP1http://www.microsoft.com/downloads/details...;displaylang=en
You should then update through Windows Update.
If you do uninstall all:
see Louis' post, on the way to do it:http://www.bleepingcomputer.com/forums/t/268334/re-uninstalling-msnet/
Most recent version should come off first.
