Yep, Cisco VPN Client didn’t work first time but there is a small registry update to make it work. The installation worked fine but after I setup an entry it will tell me “Failed to enable Virtual Adapter” during “Securing communication channel”. There is a small registry fix for this.

Open Regedit and go to:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\CVirtA

and modify the value of DisplayName key with the following

For 64 bit – Cisco Systems VPN Adapter for 64-bit Windows
For 32 bit – Cisco Systems VPN Adapter

Close Regedit and try to connect again… Voila’!
