2. Edit the Registry

This resolution is more specifically for Windows 10, 8.1, and 8. Lots of Cisco VPN users have stated that editing the DisplayName string value for CVirtA with the Registry Editor fixed the Virtual Adapter error for them. Cisco VPN users should edit the registry as follows.

1. First, open the Registry Editor by entering regedit in Run and clicking OK.
2. Copy this registry path with the Ctrl + C hotkey:

Then paste the path into the Registry Editor’s address bar with the Ctrl + V hotkey, and press the Return key.

Right-click DisplayName and select Modify to open its Edit String window.

Next, erase @oem8.inf,%CVirtA_Desc% from the Value data box. Then the Value data box should include either Cisco Systems VPN Adapter for 64-bit Windows or Cisco Systems VPN Adapter depending on whether Windows is a 32 or 64-bit platform.

Press the OK button to close the Edit String window.

Close the Registry Editor.

3. Turn Off Internet Connection Sharing

1. Some users have also confirmed that turning internet sharing off for the network adapter that provides internet for Cisco VPN fixes the issue. To do that, enter ncpa.cpl in Run and click OK.
   
2. Right-click the internet network adapter and select Properties to open the window below.
3. Click the Sharing tab shown directly below.
   
4. Deselect the Allow other network users to connect through this computer’s Internet connection option on the Sharing tab.
5. Press the OK button to close the properties window.

Those are three confirmed resolutions that fix the Failed to enable Virtual Adapter error in Windows 10, 8.1, 8, and 7.

Note that Windows 10 doesn’t officially support Cisco VPN, so it’s fairly essential to edit the registry as outlined above to get the client up and running on that platform. Ready to tackle this issue? Let us know how it worked in the comments section.
