Has anyone had any luck getting the anyconnect client ver 2.4.012 to work inside of Windows 8. I have tried the registry hack that renames the adapter name, tried running as Administrator and compatability settings. Nothing works. Evertime I run it it says the Client driver has encountere an error followed by Unable to establish VPN. Oh yeah I also tried to install the certificate after the message asked for it. Although I never had to do that in Windows 7. Still nothing. Anyone have any ideas?
