3. How To Use Cisco Vpn

An antiquated version of Cisco VPN used by a new client was being stubborn and failing to install on my machine. I was getting error 27850, stating something in my system was “corrupted”.

I had a hunch that the installer was conflicting with Cisco AnyConnect, a more modern version of Cisco’s VPN implementation, a program I had uninstalled after finishing up at a previous client.

How to Install Cisco VPN Client on Windows 10 (New installations or O/S upgrades) The instructions below are for new or clean Windows 10 installations. Users who just upgraded to Windows 10 from an earlier Windows version, will need to first uninstall their SonicWALL VPN Client & Cisco VPN client, then proceed with the instructions below.

To fix the problem, increase the value to 14 in HKEYLocalMachine System CurrentControlSet Control Network MaxNumFilters. I previously ran the Cisco VPN client and then the Sonicwall VPN client with no issues. 'Unable to manage networking component. Operating system corruption may be preventing installation.' I disabled my AVG 2011 Business firewall, anti-rootkit, resident memory, detection, etc. As well as making sure I had current network drivers (HP website.

I dumped the MSI installer log file and sifted through to find a more detailed error.

And the result was a 1MB text file. The concerning portion was:

It looked like the DNE portion of the VPN was failing to install. After some more searching I found a separate installer for DNE on Citrix’s website. I downloaded and installed the DNE installer. When trying to install it threw an error about a registry key. It was unable to modify HKLM/SYSTEM/CurrentControlSet/Services/DNE. I deleted this registry key and re-ran the installer. It went through successfully! After that I ran the original VPN installer, which also worked!

Of course that wasn’t the end of it. After importing the client’s VPN connection information, I got error “Reason 442: Failed to enable Virtual Adapter”

The mighty Google lead me to an IT That Should Just Work post solving this issue via a simple registry edit. After modifying the name of the adapter the VPN was then able to connect!

  OndrejKa, does that work if you don't have the AnyConnect license added to the ASA?

  Mine has licenses for 2 end-points running AnyConnect - I want to use them, but so far, even though I am licenses, Cisco won't give me the installer since I didn't buy the extended licenses. That said, I plan on upgrading anyway, it's nice we have a fix, but I can't have my end-users do this, I will have to hire another person just to field the VPN Installation support calls once Win 10 takes off.

  I don't see Cisco fixing this. The VPN Client has been abandoned in favor of the AnyConnect client (which requires more licenses to be purchased.) The IPsec/PSK VPN is in their vision simply for hardware connections (IP Phones, Route-to-Router, etc) not End-Users...

  Hello,
  Before doing this solution for the cisco VPN I had Forticlient VPN for another client, the moment I did this workaround the Forticlient VPN connect to the client but it doesn´t give me access to the network, I can´t reach to any device. What I did was uninstall the Cisco VPN and the citrix so it could work again. Does anyone have this problem and find a way to have both VPN´s working
