Not sure if anyone is affected by this, but Cisco has finally succumbed to pressure and released a 64-bit Cisco VPN Client v.5.07 that works on both Vista and Windows 7 64-bit os's (but not 64-bit XP, which is not widely used). It is still in beta and can be downloaded here :

by those with Cisco support accounts. I just installed it on Windows 7 on my home laptop and finally I can VPN into my work network again.
