Blender Version
Broken: 2.73 x64 official release. Can't see splashcreen
Worked: 2.72b x64 official release.

Short description of error
Blender crashes immediately after opening it. I can see the Blender window for a fraction of a second and then it closes. Nothing happens after that, there is no error or crash window or anything. It just closes.

Exact steps for others to reproduce the error
Just open it with a similar rig. However, I reported a similar error before, T39706, but it was disregarded as a fault of the unsupported Intel gpu. It turned out that I had problems with my user files, that was my fault and I fixed it deleting my user files. Nothing to do with the gpu. I thought now it could be the same, but after using other user files, and manually disabling addons, it still won't open. This is all I did:

Installing a clean copy of 2.73 x64. At this point there is no user folder at /users/admin/appdata/roaming/blender foundation/blender - Blender instantly closes

Downloading zipped versions of 2.73, both 32 and 64 bit - Both Blender(s) instantly close.

Manually copying user files from 2.72 folder to a new 2.73 folder - Blender instantly closes, but I could see the previous theme and layout configuration I had during that instant.

Disabling folders one at a time at /program files/blender foundation/blender/2.73/scripts to do some amateur debugging - Blender instantly closes, sometimes I can see some things dissapearing but that's it, it closes nonetheless.

Reinstalling the older 2.72b - It works perfectly.

Installing 2.73, 32 bit on another computer. Windows8 32 bit, 1gb of ram, Intel Atom N450, Intel GMA 3150 OpenGL 1.4 - It works perfectly

Hopefully it isn't GPU related
Since 2.72 works perfectly I don't think it is the GPU though I know you will drop support for OpenGL 1.1 in the future. In the meantime I will report it as bug. Thanks for your hard work.
