I have 64-bit drivers that install fine, 64-bit NCP (VPN) that installs fine, 64-bit WinZip that installs fine and few more 64-bit applications that install fine.
What are you have difficulty with?
I use Corporate Symantec Endpoint (not Norton Consumer) and I do not use Novastor backup. Since it appears to have a problem, can you uninstall this while you test?
