How to fix “Reason 442: failed to enable Virtual Adapter” on Windows Server 2012?

I tried to install the IPSec VPN client on the Windows Server 2012 but I when I tried to run the client I got the error message:


"Reason 442: failed to enable Virtual Adapter"

I found one fix for Windows 7 (where you have to disable the “Internet Connection Sharing” on the services list) but it didn’t work for Windows Server 2012. To fix the issue on the server platform you have to find following registry key and change the field “DisplayName” for:


HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\CvirtA

from:

@oem8.inf,%CVirtA_Desc%;Cisco Systems VPN Adapter for 64-bit Windows

to:

Cisco Systems VPN Adapter for 64-bit Windows
