Didn't want to start a new thread, so will jump here. First i wont to comment a few messages here.
We also had 0x0000005 initialization error with one application launched from the share. It is a known problem and is caused by Application and Device control policy. We had to disable it so far.
Speaking about the requirement of restart after the upgrade. Wonder, do we really need to restart machines if upgrade is done via Install Packages. SEP client icon appears and it seems to be working, it also reports its status and SEPM doesnt show, that clients should be restarted.
I had no problems upgrading clients to 11.0.4202.075 via Install Packages. Upgraded ~200 clients in a few days. I think it is more convinient than GPO and you can keep track of installations by generating report and filtering by program version. 80% of clients were upgraded in a few hours after i have set packages.

Ok. Now my problem. Now i've launched 11.0.5202.333 packages via Install Packages. I'm seeing problems with upgrading HP 6710b laptops with Vista SP2 32bit Business. Usually it slowdowns a bit computer while upgrading. If user tries to restart a computer it gets stuck on Logging off.. screen. So we have to force shutdown. This happens even when installation should be over and user tries to shut down a computer at the end of the day.
