VPN client failed to enable virtual adapter

This issue got me nuts but was able to resolve it by following solution -

Just to update, the legacy Cisco VPN client ( for x64, for x86) is working for some people. You need to apply a small workaround as explained below –

·    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.

o    For x86, change the value data from something like "@oem8.inf,%CVirtA_Desc%;Cisco Systems VPN Adapter” to "Cisco Systems VPN Adapter”

o    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

In addition, I also needed to disable the service "Internet Connection Sharing":
1. Run 'services.msc'
2. Find 'Internet Connection Sharing'
3. Stop and disable it.
