**System Information**
Mobile Intel Core i7 720QM (1.66GHz), Win7 Pro 64bit, 8GB RAM, NVIDIA GTS 360M with 1GB VRAM
**Blender Version**
Broken: Blender 2.74 64bit (Hash: 000dfc0), (blender-2.74-windows64.zip);
Worked: (optional)
**Short description of error**
If the option User Preferences | File | Load UI is unchecked, double clicking or dragging and dropping a .blend file over the executable blender.exe causes Blender to start up and close immediately.
**Exact steps for others to reproduce the error**
What happens is that with the current version 2.74's blender.exe set as the default application to open .blend files when you double click on a .blend file or even dragging and dropping it over the blender.exe program, Blender starts up but then closes immediately generating the following blender.crash.txt log file:

So I restored all the default settings and checking all my changes to the preferences one by one I found that what apparently seems to cause this behaviour is the "Load UI" option if unchecked. If you reinstate it (checked) opening automatically the file .blend as well as dragging and dropping the .blend file over the executable (blender.exe) works fine. I cannot be sure anyway that other setting might produce the same problem, at least this is what I found out.
