Using Cisco VPN Client in Windows 10

 

GOAL:  To be able to continue using the legacy Cisco VPN Client program on Windows 2010.

In case you have a laptop or computer that is running Windows 10 in it, chances are, then you will experience any of these behaviors when you try to connect to the Cisco VPN:

  1. The already installed Cisco VPN client for the previous Windows 8.1 or Windows 7 PRO installation will make your network connections disappear.
  2. The already installed Cisco VPN client for the previous Windows 8.1 or Windows 7 PRO installation won’t work and will show errors once it is run.
  3. If it’s not yet installed, you will encounter an error at the latter part of the installation and it won’t continue.

Here’s the workaround to get your Cisco VPN to run and have you connected to the office network in no time.

PREREQUISITES:

Download the following programs:

WinFix.EXE – ftp://files.citrix.com/winfix.exe

GVCInstall64.MSI – http://help.mysonicwall.com/Applications/vpnclient/

Vpnclient-winx64-msi-5.0.07.0440-k9.exe – You must have this already since you were already using the VPN client in the older OS.  If none, you may download it in the internet.  Just take precaution on the source web site and be very wary of viruses and malwares.  As of now, I cannot recommend a web site to download this program.

Follow these steps:

  1. Uninstall the current Cisco VPN client from the computer (if it was already installed).
  2. If you see any DNE updater software in the programs list, uninstall it.  Normally, you will find it if you have a working VPN and you’re using windows 8.1.  It’s not normally found in Windows 7.
  3. Run the WinFix.EXE program.
  4. Reboot the computer.
  5. Run GVCInstall64.MSI.  This is a Sonicwall program.  You only need a small piece of the program but you still have to install the whole thing.  At the end of the installation, do not check the checkboxes regarding starting up the program when windows start.
  6. Reboot the computer.
  7. Run the vpnclient-winx64-msi-5.0.07.0440-k9.exe. When you see the Extract the program window, extract it first to a temporary folder of your choice.  Do not proceed in installing it as you will encounter an error when you install it through the .EXE program.
  8. Locate the temporary folder where you extracted out the Cisco VPN client program and look for the MSI installer. Run it and complete the installation.
  9. On Windows Services, look for Internet Connection Sharing and set the STARTUP TYPE to MANUAL or DISABLED. Do not run it as it will conflict with the VPN program.
  10. In a similar manner, look for CISCO VPN Service and set the STARTUP TYPE to AUTOMATIC.
  11. Run Regedit and go to the following hive – HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\CVirtA.  Select “Display Name” and modify it using the following:

“@oem8.inf,%CVirtA_Desc%;Cisco Systems VPN Adapter for 64-bit Windows” to “Cisco Systems VPN Adapter for 64-bit Windows”

Normally, it is already set to “Cisco Systems VPN Adapter for 64-bit Windows” so you don’t need to change anything.

  1. Reboot your computer test your VPN.
