Hi fellow Chris,
I'm pleased to see someone else with perhaps the same issue... fresh installations of SEP 12.1.5, unmanaged, unable to update (though not issues with the installation procedure).
In my case, both are installed on fresh installations of Win 8.1 64-bit, from MS DVDs (not images) (one straight Win 8.1, the other Win 8.1 Enterprise). All Windows Updates performed prior to SEP installation. Two different models of Dell laptop. I've tried over wired, wireless and even ADSL wired and all fail.
(Note: a Win 7 Enterprise laptop with version 12.1.4 works over wireless - the Win 7 machine is not a fresh install, so will already have a recent update, but it did request updates just now and that went through successfully. Also, my desktop is Win 8.1 Enterprise 64 bit, with 12.1.4).
'Virus and Spyware Protection definitions are out of date.' > I click on the 'Fix' button to rectify this > I click 'OK' to the confirmation box. If I look at Task Manager I can see 'Symantec Service Framework' is using the CPU (hovering around 30-40% CPU for around about a minute).
In the Client 'System' logs I get plenty of "symantec endpoint protection postsession callback failed (208)". And similar errors to your errors - 2 updates to install, 0 installed, etc.
On one laptop I tried 12.1.4 before uninstalling, rebooting and trying 12.1.5. Both versions have the same issue.
I've used 12.1.4 many times before when setting up Win 8.1 laptops manually from scratch and not had an issue with LiveUpdate. This seems to be a recent thing (within last month maybe?). Could there be a Win update mucking things up? Chris - did you perform and Win updates before installing SEP?
Sadly I've had to give the laptops to the users already, so don't have them to test at the moment.
Before I had to give them back, I got to run the Symantec Help tool on one... two things came up with red circles / white crosses through them:
"System does not meet the requirements for Symantec Endpoint Protection 12.1: Remote install".
"Disable the Windows AutoRun feature".
(Attached is the output file from the scan).
Otherwise fine.
Any thoughts? Would you folks at Symantec have a freshly built Win 8.1 machine to-hand, all Windows Updates performed, and see how it gets on with 12.1.5 fresh installation...?
Chris
