PLease share with me your expirience on the listed case
How Virus Scan 8.8 can be used without ePO management console?
It is not clear is it possible to setup the license on VS without using of ePO.
IIRC the product documentation available on your grant-downloads page or the McAfee KB should detail installing the product in a stand-alone/non-ePO manner. I do know that when you install VSE stand-alone, you indicate your license type at that time (IIRC scripted unattended installs can't specify perpetual licenses). You'll then have to configure and manage the individual installs after that....someone else may have shortcuts or tips for that end of the process.
