Solution: Cisco VPN on Windows 10 Error 442 "Failed to enable Virtual Adapter"

On my Windows 10 PC the Cisco Systems VPN adapter (not AnyConnect) worked for a bit then started throwing error 442 "Failed to enable Virtual Adapter". Even after uninstalling and re installing the application I still encountered the error.

I finally found a fix on a post in the Cisco Support forums here

The solution is this:

  1. Open Registry editor by typing regedit in the Run prompt
  2.  Browse to the Registry Key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\CVirtA

  3.  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 "@oem20.inf,%CVirtA_Desc%;Cisco Systems VPN Adapter” to "Cisco Systems VPN Adapter”

    - For x64, change the value data from something like "@oem20.inf,%CVirtA_Desc%;Cisco Systems VPN Adapter for 64-bit Windows” to "Cisco Systems VPN Adapter for 64-bit Windows”

That fixed it for me. Now my VPN connection works perfectly.
