The problem with Cisco VPN client is that it will not let you install it from a network location.
To solve this problem I used a script to copy the files to the local computer and then installed it from there.
xcopy Ciscovpn “%TEMP%” /E /C /I /Q /H /R /Y /Z
START /WAIT msiexec /i “%TEMP%\vpnclient_setup.msi” /qb!- Reboot=Suppress
If you want you can use make and model to always have it install if it is a laptop.
