If you see the following screen with a message saying: “ Secure VPN Connection terminated locally by the Client. Reason 442: Failed to enable Virtual Adapter”.
Proceed to step 1.
1. Open the registry editor and navigate to:
HKEY_LOCAL_MACHINE > SYSTEM > CurrentControlSet > Services > CVirtA
Locate the DisplayName > Edit its value > Delete all the text to the LEFT of “Cisco Systems VPN Adapter for 64bit Windows.”
2. So it looks like this.
3. It should now be up and running.
