Cisco VPN client error: 'Reason 442: Failed to enable virtual adapter' on Windows 8

Today after installing Microsoft's new OS on my main development PC and trying to open a VPN connection to my server, I was hit with this little gem:

Reason 442: Failed to enable virtual adapterSo Cisco VPN Client would not, under any circumstances open up a VPN connection, meaning I couldn't access my server, meaning the customer who was currently complaining couldn't have their glitch fixed.  At times like this my blood goes on the boil.  After a relentless search here's what I did to fix it...

  1. Make sure the device is Enabled within Device Manager
    Enable Cisco VPN Adapter
  2. Open RegEdit (Start > Run > "regedit"), and navigate down to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\CVirtA
  3. Double click DisplayName
  4. Then change the Value Data to remove all the text up to and including %; (including the semi-colon)
  5. Press OK and then close RegEdit
  6. Close down Cisco VPN Client and restart it

 And that's that little issue sorted.  Hope that works okay for you too. Good luck :-)

Dude, you are the man!  Everyone had this fix of the regedit out here, but you were the only one that nailed it!  Enabling the adapter was spot on! Thanks! I was ready to dump Windows 8 and go back to Windows 7, but you saved me.

This did not work for me, I still get the same error, yet this seems to be the only solution that I can find on this issue.
Does anybody have any other suggestions on how to fix this?
Though if I run the diagnosis option on the CISCO virtual adaptor....it states that it "doesn't have a valid IP configuration" and does not fix it.....
If anybody has ANY suggestions, please e-mail me at batmanssf[REMOVE]@gmail.com   thank you.

Erich,
First make sure you are running the latest version of the Cisco Adapter software.  The old versions do not work on Windows 8, only the most recent version will run at all.  Following that I'm out of ideas I'm afraid as I no longer use the software.

I found another solution, and this fixed my problem.
I had Internet Connection Sharing Enabled on my Wi-Fi Interface.
Once I disabled this, restarted the VPN Client, and Press Connect, it worked - Connected! Awesome!
