In the comments of that post yaz points out that NCP has a Beta Client that works on 64-bit clients – and that includes Windows 7. It also supports 3rd party VPNs and that includes Cisco.
The NCP beta client is available via this page. Install was simple and there is even a UI to import your existing Cisco VPN profile.
It appears to be a 30 day trial – which is a bit odd for a beta product. It does appear to work though. I’ll give it a good work out over the next couple of days and report back.
