Am running embedded database server on Windows 2008 platform, all prerequisites met, began upgrade process around 4 hours ago, screen still reports "Embedded database upgrade in progress, this may take a while" and progress bar has not moved. Very low cpu usage, less than 5 per cent, but there does appear to be a lot of disk activity. Is there any way to tell something is actually happening, how long does this normally take? 4 hours seems a long time, organization is about 2000 registered computers and 4000 users. At what point should I assume something is wrong, and what to do then, the cancel button is grayed out and am concerned as to ability to recover to 10.3.4 Thx in advance, Dana Reed
