For months now I have been unable to connect to the iTunes store on my Windows 7 64-bit PC. Tried everything. Windows firewall is replaced by McAfee firewall and I enabled full access there for iTunes. What else can I do to fix this?

Answer 1

Can someone please respond to my request for support?  I tried the provided correct answer at https://discussions.apple.com/message/11561783#11561783  but it did not work. 
I also got a MSFT tech support person to remotely look at my machine, for what its worth, he said the registry file is fine and to contact Apple support.
Any help would be very much appreciated.
