I have installed Windows 8 Release Preview while ago. And I am doing all my work on this as it supports all software which I was installed on my Windows 7 version. Everything going great except Cisco VPN client. For getting this to work I have spend almost 6 hours by hacking the registry keys, change adapter settings and installing and uninstalling the VPN client, reboot my PC. But, no luck. The error which I am getting always are:
1 12:54:15.440 06/24/12 Sev=Warning/3 CVPND/0xE340000C
The Client was unable to enable the Virtual Adapter because it could not open the device.
2 12:54:15.455 06/24/12 Sev=Warning/3 CVPND/0xE340000C
The Client was unable to enable the Virtual Adapter because it could not open the device.
3 12:54:15.455 06/24/12 Sev=Warning/2 IKE/0xE300009B
Failed to active IPSec SA: Unable to enable Virtual Adapter (NavigatorQM:936)
4 12:54:15.455 06/24/12 Sev=Warning/2 IKE/0xE30000A7
Unexpected SW error occurred while processing Quick Mode negotiator:(Navigator:2263)
Solution 1:
After a bit of research and information from another community found the Cisco VPN is writing wrong values in the registry key for DisplayName string.
To fix the issue, we should change the value to below:
Open registry editor [From Windows Run type regedit] and move to the location: HKLM\SYSTEM\CurrentControlSet\Services\CVirtA
Now, try to connect to VPN and it should work without any issues.
Solution 2:
I have installed VPN Client from Shrew.net site. This can be available here Download Shrew VPN files. This also supports the Cisco VPN PCF files. Once I installed and imported my PCF files, it’s working in a second.
Hope, this will save your good amount of time! Enjoy.

- For x86, change the value data from "@oem8.inf,%CVirtA_Desc%;Cisco Systems VPN Adapter" to "Cisco Systems VPN Adapter"
- For x64, change the value data from "@oem8.inf,%CVirtA_Desc%;Cisco Systems VPN Adapter for 64-bit Windows" to "Cisco Systems VPN Adapter for 64-bit Windows"
Now, try to connect to VPN and it should work without any issues.
