SEP 12.1 RU2 client install

Created: 09 Jan 2013 • Updated: 11 Jan 2013 | 6 comments
This issue has been solved. See solution.


We upgraded SEPMs from SEP 11 RU7 MP2 to SEP 12.1 RU2 (confirming suppoted migration path).  Exported client packages for 64-bit and 32-bit platform, with the installation type to "show progress bar only".  Installation goes fine and install process runs liveupdate which also completes, but LiveUpdate Status windows does not close by itself.  Initially  I though it could be time issue and tried couple of clients over hrs and even over night, even then one has to click "close" button to close startus window.

There  was no such issue when we used "unattended" in packages for SEP 11 in any of its builds.

Any body experienced such behavior.

Thanks & Regards,

Did you try it with a silent install? That should work.

Are you using the MSI?

yes, you need to click on close button.

I believe you would have to click on "Close" button during the first session Liveupdate that happens after installation/ migration.

A restart of machine may be required as well.

Any particular reason, the Auto-upgrade feature is not chosen for Migration??

Did you follow the Best Practice Article:

Best practices for upgrading to Symantec Endpoint Protection 12.1.2

Hope that helps!!

Yes, the silent would work.  But we have to use "show progress bar only" due to our environment, 100% new install are done by either helpdesk staff or users' themselves. Being a higher education institute only 60% machines are in domain.  We will use auto-upgrade for existing clients.

It was not like this in any SEP build, that we used starting from SEP 11 MR3 to SEP 11 RU7 MP2.  Liveupdate status windows would close both during first install and if liveupdate is run from SEP GUI.  But in SEP12.1 RU2, "close" button needs to be clicked for Liveupdate Status windows to close.  May be we have to educate users for this new behavior.

Best wishes,

This may have than changed in SEP 12.1

You could stop LiveUpdate from running if that would work. Defs would than update from SEPM or GUP. The issue is they may be out of date until that update happens.

The version of LiveUpdate in 12.1 is different from the old LiveUpdate in V11. This is why the dialog box doesn't close by itself. I suggest either educating your users, or using the instructions to suppress the LiveUpdate after install, since the client is going to immediately check-in to SEPM and get content anyway.
