Cisco VPN Client and Windows 8

Cisco VPN Client fails to enable virtual adapter in Windows 8, it happens to me first time I install  Cisco VPN in my new Windows 8 Laptop, the below workaround was a permanent fix for this problem:

• Open Registry editor by typingregedit in Run prompt
•  Browse to the Registry Key    HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Services\\CVirtA
• Select the DisplayName to modify, and remove the leading characters from the value data upto "%;" i.e.

===========================================================

• For x86, change the value data from something like "@oem8.inf,%CVirtA_Desc%;Cisco Systems VPN Adapter” to "Cisco Systems VPN Adapter”
• For x64, change the value data from something like "@oem8.inf,%CVirtA_Desc%;Cisco Systems VPN Adapter for 64-bit Windows” to "Cisco Systems VPN Adapter for 64-bit Windows”

 Try connecting again

Note: the legacy Cisco VPN client (5.0.07.0440 for x64, 5.0.07.0410 for x86) is working for some people.
