Per Cisco's website you can now get a copy of their Beta x64 based IPsec VPN client. Statements made by Cisco in the past have stated that there would be no 64-bit IPsec VPN client released ever. I guess they finally sucked it up, and listened to their customers, and made a 64-bit version for IPsec vpn's. Cisco does have a new vpn technology that works on 64-bit computers but the licensing for it is per user, not per total number of allowed connections, which can lead to a pretty pricey investment. Thank you cisco for pulling your head out of your ass and giving us what we need.

Here's one of the statements from an article on their website relating to IPsec vpn clients "Cisco VPN Client Version 5 is available for 32-bit Windows Vista. There are no current plans to provide 64-bit support for the Cisco VPN Client but 64-bit support is available for the Cisco AnyConnect VPN Client."
