Cisco VPN to work on Windows 8 x64?

Error:   Secure VPN Connection terminated locally by the Client. Reason 442: Failed to enable Virtual Adapter. Connection terminated.

This problem occurs due to a registry error in the installer. All you need to do is fix the following registry key:

Open regedit.exe, and go to

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\CVirtA

Edit the DisplayName value to remove the gibberish before "Cisco". The value by default will be something like:

@oem18.inf,%CVirtA_Desc%;Cisco Systems VPN Adapter for 64-bit Windows

Edit it to just say:

Cisco Systems VPN Adapter for 64-bit Windows
