create a new system restore point first by going to programs> acessories,> system tools> then system restore, then highlight create a new restore point and name it if you wish.If anything goes wrong you can restore your system to the restore point you just created. But be warned any wrong moves in your registry can cause your pc not to boot. I would talk to Norton first, they might suggest reinstalling the Norton software
The answer is in Skidzy's second link. Just set Norton to ignore the "problem". You don't need to do a system restore and you don't need to reinstall the net framework. You don't need to download the apparenly missing dll file either.
click here and read martynl's post about two thirds down. From his post, "...Norton WinDoctor is wrong. It incorrectly reports that msvcr80 is missing when in fact it is correctly installed in the WinSxS directly in the windows. folder..."
