Windows 8 Cisco VPN error - Reason 442: Failed to enable Virtual Adapter

I did a clean install of Windows 8 on my laptop and was reinstalling software. I was importing and attempting to connect to a client that used a Cisco setup but was hitting the error: "Reason 442: Failed to enable Virtual Adapter." seen in Figure 1.

SOLUTION: Needed a registry change for Cisco because of an issue with the program on Windows 8. Solution at below in post:

Figure 1 - Reason 442 error

Things went down in the following fashion:
  • I wasn't already on the network via hard wire. Of course not
  • The VPN Network adapter was enabled. Didn't work
  • Make sure the VPN client was on the latest and greatest release. Sure is
  • Clicked on diagnostic for troubleshooting. Got the information in Figure 2
  • Ran 'ipconfig \release' and 'ipconfig \renew' in command prompt. Nothing...
  • Made changes to the registry per the below post. WORKED!
Here are the steps to making the registry change to fix this Reason 442 error.
  1. Navigate to the registry
    1.  Hit Windows Key+R (This opens the Run prompt)
    2. Type 'regedit' in the field and click 'OK' (or just hit the enter key
  3. Locate the DisplayName key (Figure 3 below)
  4. Change the value to the following
    1. x86 (32-bit) - "@oem8.inf,%CVirtA_Desc%;Cisco Systems VPN Adapter” to "Cisco Systems VPN Adapter”
    2. x64 (64-bit) - "@oem8.inf,%CVirtA_Desc%;Cisco Systems VPN Adapter for 64-bit Windows” to "Cisco Systems VPN Adapter for 64-bit Windows”
If that doesn't work, you can change the settings back but it won't do anything for you.

Its that simple!
