To successfully use Connectra Portal ICS (Scanning with compliance policy ) activeX and Java VM should be installed on the pc, If the two components are successfully installed another component deployment shell installation begins , if you have a problem with the two prequiste you cant install the deployment shell and you get the warning deployment shell internal error.
Solution: unregister the pc from windows domain (you wont deal with GPO,User Profiles,Security Templates , etc. ) unistall everything and do a fresh install.
Also, ICS components reside at /opt/CPcvpn-R66/htdocs/ICS/components for R66.1 server ,replace them by the new files from your test vm
and apply the command # cvpn_port_utility.csh.R66_01
