do not work on 64 bit systems. You'll find that you have more problems than just your antivirus. Many programs don't have versions for 64 bit but Symantec DOES have programs for 64 bit so perhaps if you contact Symantec with your product key and explain the problem, they MIGHT help you out.
I have a copy of Symantec Antivirus Corporate Edition that I installed on my 32bit XP Machine. I just built a brand new Vista64 Machine.
I want to install the Symantec program on my newer machine. However I recieve this error message when attempting to do so...
Symantec AntiVirus Client Installer Information
The win32 version of the installer can't install Symantec Client Security on a 64 bit OS.
...does anyone have any advise about a workaround or what my next step should be?
