Problem:
Windows 8
Cisco VPN client 64-bit
you install and configure everything correctly and suddenly after typing credentials error appears:
Reason 442: Failed to enable virtual adapter
And here is the reason, there is a wrong registry value created during the installation of your client. Who knows why? The incorrect registry key contains invalid DisplayName:
@oem4.inf,%CVirtA_Desc%;Cisco Systems VPN Adapter for 64-bit Windows
You should have: Cisco Systems VPN Adapter for 64-bit Windows
So, go to:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\CVirta
and change the DisplayName value.
