Hi Anna.
Safe Mode is accessed by pressing the F8 key on your keyboard repeatedly
after you initially start your computer, around the time the BIOS is done
posting, or presenting the initial screen , when you power on. You will see
a list of options, in which you have to use your Arrow Up or Down keys to
make a choice. Once you enter Safe Mode, you'll see your Desktop, and all,
but not all services and drivers will have been loaded, and things might
appear slightly gigantic. The display driver you normally use, for example,
has been disabled. Once you have tried uninstalling NET Framework Version
1.1 Service pack 1 in Control Panel, to exit Safe Mode, just restart your
computer as you normally would, using the Start Menu.
If that doesn't work, or you feel you don't want to go that route, just try
going to the next step.
Download and use (Run as Administrator) the Windows Installer CleanUp
Utility, and remove all references to .NET Framework Version 1.1 Service
pack 1 (only!).
Then reinstall .NET Framework Version 1.1 Service pack 1:

Then run Windows Update again, to install KB929729.
