Upgrading the vpn client to installshield vpn 4.8. If we do an install with the OEM.INI set to SilentMode=0 and Reboot=0, the application will not allow the client to be later removed by clicking Add/Remove - Remove or from the Start Menu - Uninstall VPN Client. If we do a manual install without these settings, the Add/Remove works fine. Is there a way to re-enable the Add/Remove after doing and silent install?
