ok I have a bug in the blender when I run the application it displays in writing command prompt, then the directory where this error at the end directory appears blender.crash.txt and the program closes I had no a connection problem with the blender until that time more this problem affect me to use the blender

Well, as explained on the report page, we need more info here, like your OS version, GPU & drivers info, the exact blender version, please also attach that blender.crash.txt file here, as well as what's printed in the command line.

My blender.clash displays # Blender 2.72 (sub 0), Commit date: 10.21.2014 11:38, Hash 9e963ae.
my OS windows ,7 gpu ati 760 and blender version 2.72b.
My command line closes very fast so I can not capture the print, shows writing C: \ Users \ PC \ AppData \ Local \ Temp \ blender.crash.txt

Thanks for those info. Please run Blender from a command line, that way it will remain open and you'll be able to copy what's in it.

And please attach here that C:\Users\PC\AppData\Local\Temp\blender.crash.txt file.

Also, please try our latest build from our buildbot, official blender 2.72 is becoming rather old already.

sorry, it was a problem in the drivers downloaded a program and my drivers repaired
