When running the Cisco VPN client on a Windows 64bit OS, it seems to never install correctly and will fail to connect.
Secure VPN: Connecion terminated locally by the Client. Reason 442: Failed to enable Virtual Adapter
It seems to be an issue with how the installer registers the network device for the Service. It’s an old issue that has been popping up for YEARS.
The fix is relatively simple.
- Open Regedit
- Browse to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\CVirtA
- Check the DisplayName key and it will have a value like “@oem22.inf,%CVirtA_Desc%;Cisco Systems VPN Adapter for 64-bit Windows
- Edit and remove the first part of the entry to leave “Cisco Systems VPN Adapter for 64-bit Windows”
- Restart the VPN Client software and it should now work
