Cisco VPN client error 442 on Windows 8

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.
