NIS 2011 Removal & Reinstall Windows 7 64

I bought a laptop last month that came preloaded with a trial version of NIS 2011. I  have a NIS 2011 that I puchased that I would like to install.

 

I know how to uninstall & reinstall NIS 2011 from Windows XP,but I am not sure how to uninstall & reinstall with Windows 7 64.

 

 

Can you please tell me what needs to be done? And do the Symantec entries need to be removed from the Program&Program X86 files? Registry entries also?
