After upgrading from Windows 8 Pro to Windows 8.1 Pro, the Cisco VPN NIC driver stopped working.
The driver wouldn’t update via Device Manager. I uninstalled the Cisco VPN Client 5.0.07.0290 then rebooted the computer.
When I tried re-installing the Cisco VPN Client 5.0.07.0290, the Cisco VPN Client would terminate with the following error:
Error 28000: Before installing the Cisco Systems VPN Client 5.0.07.0290, you must uninstall the previous version of Cisco Systems VPN Client 5.0.07.0290, using the Add/Remove Program Files option in the Control Panel. then restart your system.
Start “Regedit” as an Administrator:
Search for “Deterministic Networks” and delete it.
e.g. HKEY_LOCAL_MACHINE\SOFTWARE\Deterministic Networks
Search for the following keywords in the registry under the “Uninstall” or “Components” folders and delete any related entries.
