Lightroom 5 crashes on Windows 7 64 bit will periodically crash about once every hour. Never had problems with Lightroom 4.
I have a fairly small (3000 images) catalog. The catalog was created with lr5. I've tried other catalogs and also having the issue.
I'm using dual displays and am in the library module in survey mode. The second display is showing images in Live Loupe View.

I was crashing often on Windows 7, and after reporting it, Adobe technicians identified a dubious ui.dll file.

I had the exact same issue on my windows 7 machine. 16 gig of ram, AMD phenom 6 core processor. Tried lots of things including reinstalling Lightroom, patching windows, updating driver, reseating memory and processor. I then noticed while running sys monitor and a CPU temperature measuring program that the processor was hitting 70 degrees while performing certain tasks in Lightroom. The max recommended temp for that processor is 70 degrees. And one should run a processor at 20 degrees below the rated max. It was odd since the processor had an upgraded cool master heat sink and the fan was running at full speed. Something must have failed in those heat pipes. Anyway, I changed the heat sync and fan assembly for the stock amd heat sink that I still had. The CPU runs at 50 degrees at full load. So far no crahes after 2 hours of use. I will update if the machine crashes.
