How do I install VSE via ePolicy Orchestrator?
Add the installation package to your repository, then create/modify a Deployment Task (see your ePO 4.6 or ePO 4.5 documentation for instructions).
NOTE: The Deployment Task allows for command line options to be specified too. This allows you to make simple changes to the installation, such as not installing a particular feature. For a complete list of options, see PD22944.
Also recommend you to go through KB71642 - FAQs for VirusScan Enterprise 8.x, to address your other queries related to VSE.
