Fix Cisco VPN Error 27850 on Windows 10

After my wireless issue on the Windows 10 I want to install newly the older Cisco Systems VPN Client.

While installing the client you may get an error saying Error 27850: Unable to Manage Networking Component Operating system Corruption may be preventing installation.

Wireless Networks Missing After Windows 10 Upgrade 6


  1.  Ensure you are using the latest version of Cisco VPN Client: the most recent version is now
  2. Pre-Install the DNE software: the issue seems to be with Cisco’s installer not being able to make the required changes to fully add the DNE driver to the system. You can get this from Citrix’s site here:
  3. Install the Cisco VPN Client: the Cisco software should now work.

Now you should be able to add your VPN profiles and start correctly.

UPDATE: if you get an error 2738 during the software upgrade or installation use the following command to delete a registry key:

reg delete “HKCU\SOFTWARE\Classes\Wow6432Node\CLSID\{B54F3741-5B07-11CF-A4B0-00AA004A55E8}” /f
