Hi,
We are installing the SEP 14 onto a group of computers that will not connect to the internet. However, after installation, we are not able to perform a scan as the definition updates are missing. Once we have downloaded the latest updates from the Symantec website, we are unable to install them onto the machine and got an error saying:
"Your virus and spyware definitions are missing or corrupted". This is the first installation and we have not installed any def updates before, so there should not be any corrupted files, unless it's the one we tried to install.
I've also made reference from some of the answers in this community to stop the SEP service, "delete" the definitions (which were not on the machine btw) and edit the registry (also not found) and restart the SEP service.
