If you did not select the option to install/upgrade CTA during server installation, you can do so from the web console. Before installing/upgrading CTA, deploy the client certificate to clients.
A Certificate Authority (CA) server generates the client certificate file. Request a certificate file from your Trend Micro representative.
When you are ready to install/upgrade, check the version of the CTA to be installed in Cisco NAC > Agent Management, then install CTA to clients in Cisco NAC > Agent Deployment. The Agent Deployment screen also gives you the option to uninstall CTA.
Install Windows Installer 2.0 for NT 4.0 on OfficeScan clients running Windows 2000/XP before deploying CTA.
