What is wrong with Cisco? They put out an installer file that requires a registry edit to work correctly!!!
Below is what I did to get the Anyconnect client to work on Windows 8.1.
UAC accept box
2nd UAC accept box
Find this registry key:
Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\vpnva
Deleted everything to the left of Cisco.
Reload
Added software to Cisco ASA’s that was missing and I was successful in getting connected with the Full client on my Windows 8.1 computer.
