When trying to install the Cisco VPN client on Windows Vista, you might get the following error:
Error Loading C:\Windows\System32\csgina.dll
This is because GINA (Graphical Identification and Authentication) is no longer supported in Windows Vista. When you are running Windows Vista and trying to run a program that uses csgina.dll (dll for GINA), it will fail. The easiest way to resolve is to download a newer software version from the manufacturer’s website
