hi mr.killam ,
Are you creating a task sequence for OSD? or created a package and advertise to all client machines? Try to deploy the framepackage fist, once it installed it will communicate with the ePO server and installed virus scan.
i have created the package but not advertised it to clients except through the advertise to task sequence check box. i had made it part of the OSD task sequence.not sure what is different. i have not even got the AV to install correctly... i tried a wide varitey of things. i went through the destructions and installed the setupvse with the /q which didnt work, i am in the progress of trying the /quiet switch. now one thing does come up. during the task sequence i can press F8 and get the command window and install it using the /quiet and a box comes upasking if i want to remove windows defender? i am wondering if this might have something to do with it. if the box is silent and doesnt appear then it could be erroring out that way.
I will keep plugging away at this funny thing.
