Cisco VPN Client on Windows 10 [SOLVED]

Here’s how to get it working in 2 easy steps:
1. Download and install the Sonicwall 64-bit VPN client from HERE (as of this writing).
2. Install the Cisco VPN client.  Edit:  If you get an error that it cannot run on this operating system then just extract the .exe file and run the .msi file.  Problem solved.

• 32-bit Windows 7/Vista/XP VPN Client (version 5.0.07)
• 64-bit Windows 7/Vista/VPN Client (version 5.0.07)

The first two steps worked for me without the need for registry edit.  I checked and the settings were already spelled correctly on my machine.  Full disclosure my systems are clean Windows 10 installs without being upgrades.
Without installing the Sonicwall client first you will get Error 433 after trying to connect.  Checking the logs shows that it cannot download the key to complete the secure connection.
What happens is that the Sonicwall client adds the DNE Lightweight filter network client on the machine.  I tried getting it directly from Citrix and installing it that way but was unsuccessful.
Using this method you can now get some more use out of the Cisco VPN client.  If you prefer you can uninstall the Sonicwall client afterwards.  I’ve been told by several people that the DNE software remains even after the Sonicwall client is removed.
BUILD 1511 EDIT:
I’m getting a lot of feedback about networking being broken after 1511.  I would highly advise you remove the Cisco VPN client and Sonic Global client software prior to installing build 1511.
I have now upgraded three different systems to 1511.  By removing both the Sonicwall and Cisco VPN software first, I had zero issues with it working properly afterwards.
However if the upgrade went through already, here’s what you can do to help mitigate these issues.  There’s no guarantee this is going to work but I have had two instances where the Cisco VPN software was removed by the 1511 upgrade and this worked after following the steps above.
You will need to reset all networking on Windows 10.  Luckily this is pretty easy to do.
– Open an administrator command prompt
– Run “netcfg -d”
– Reboot and reconfigure your networking as needed.
Here’s a sample of the output you will see:

We are going to reboot now to complete the clean up. Save all of your work.

Press any key to continue…
I hope this helps out with the additional headaches caused by 1511.  As always if I find any more useful information with future updates to Windows 10 that affect this software, I’ll be sure to update the post.
