Windows vista is re-installed, can I uninstall Norton to save the 1 pc licese?

Hi, thanks for your help in advance!

 

As the title said, my desktop pc downed, after I tried to re-install Windows 7.

 

I believe it's compatibility issue with Nvidia 8800GT with windows 7.

 

anyway, the thing is I should have uninstall norton Internet Security 2011 before I re-install Windows 7 to save the 1 pc license.

 

BUT, now after the computer failed to boot with Windows 7, I installed Windows Vista, which succeded!

 

BUT, now the Norton SEcurity is in OLD WINDOWS file.

 

HOW can I uninstall this Norton Security from my computer to resurrect? my 1 pc license???

 

Thanks!
