Norton Antivirus Corporate Edition Versi

Hi,
I have found that whenever I try to install Norton Antivirus Corporate Edition Version 7.6 on an Windows XP machine, I get an error message warning me of compatibility problems with the Windows Version I’m using. I would like to know are there any patches to fix this problem ? or are there any newer versions of the Norton Antivirus Corporate Edition available on the market that can work with Windows XP on PCs ?
