How to get Cisco VPN client to work in Windows 8

September 9, 2012

When trying to connect a Cisco VPN client within Windows 8 it will fail with the following error:

“Failed to enable Virtual Adapter”

The solution for that is to do a workaround in the Windows 8 registry:

  • win + r and type “Regedit” in the Run promt
  • Browse to the Registry Key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\CVirtA
  • Select the DisplayName to modify, and remove the leading characters from the value data up to “%;” i.e.
  • For x86, change the value data from something like “@oem8.inf,%CVirtA_Desc%;Cisco Systems VPN Adapter” to “Cisco Systems VPN Adapter”
  • For x64, change the value data from something like “@oem8.inf,%CVirtA_Desc%;Cisco Systems VPN Adapter for 64-bit Windows” to “Cisco Systems VPN Adapter for 64-bit Windows”

Then you could try to connect the Cisco VPN client again.
