"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

That is a fairly recent version of SEP (and I have used it), so it should update.

1. Was this installed as "Managed" and do you have a connection to the managing server?  That would be one reason.

2. Was this installed as "Unmanaged"?   If so, consider uninstalling SEP completely, restarting and then re-installing it. Make sure on re-install that it launches Auto Update.
