ok, please help me to understand why 2.71 work? Does it have the dependency to SDL and OpenAL too?

solved: it is the antivirus Sophos that block two DLL:
D:\program files\blender foundation\Blender\OpenAL32.dll
D:\Program Files\Blender Foundation\Blender\SDL.dll
D:\Program Files\Blender Foundation\Blender\SDL2.dll
as are categorized as "GAME". I disabled the Antivirus and work 2.73 too.
The strange thing is that on another collegue PC, with WinXP and the same Sophos antivirus, Blender 2.72b work, when on my PC 2.72b is blocked like 2.73.

downloaded now the 64 and 32 bit .zip files. Some error.

2.73 blender-app.exe:

did you changed something in the build generation process or added a dependancy on Blender after release 2.71 ?

then I deleted "msvcp120.dll" and "msvcr120.dll" files, and repeated the 8 combinations, same result

ok monspaced text doesn't work, the intention was three columns

I just tested 8 combinations:
`

opengl32.dll --factory-startup executable

no no blender.exe
no no blender-app.exe
no yes blender.exe
no yes blender-app.exe
yes no blender.exe
yes no blender-app.exe
yes yes blender.exe
yes yes blender-app.exe
`
all lead to the same error.

this is the Path env var seen by the console where I run blender.exe and blender-app.exe:
Path=C:\Windows\system32;C:\Windows;C:\Windows\System32\Wbem;C:\Windows\System32\WindowsPowerShell\v1.0\;C:\ProgramData\Oracle\Java\javapath

what is the difference between "blender.exe" and "blender-app.exe" that I found on Windows installation?
I cannot find two binaries on my linux installation

tried to remove Blender profile (settings) on de-install, delete again:
D:\Program Files\Blender Foundation\Blender\2.73
then reinstall 2.73, same result.

I tried also to de-install Blender (keeping settings), delete the directory:
D:\Program Files\Blender Foundation
D:\Program Files\Blender Foundation\Blender\2.71
D:\Program Files\Blender Foundation\Blender\2.73
that remain after de-install, where 2.71 is about 90 MB with a full python\lib directory sized 20 MB.
then reinstall 2.73 64 bit only, same result

the bad thing is that no output is sent to the console, so how to debug the trouble?

no luck, new VGA driver, same result.

fortunately does happen for Blender only, seems other user experience trouble with all .exe and Explorer too:

another curiosity: you asked me to install the VCruntime of Visual Studio 2013. Do you generate the Blender for Windows executable using a non free compiler suite?

a curiosity, the "http://download.blender.org/ftp/sergey/softwaregl/win64/opengl32.dll",
is a software render version of the OpenGL whole libraries?
If so, on Windows it is supplied with the VGA driver, the OS, some applications, compiled by someone, or from where?
thank you

which tweak OGL settings I had to change in UserPreferences, System tab?

Windows update say: your system is up to date.
Tomorrow I will update the VGA driver.
Any other suggestions?

D:\Program Files\Blender Foundation\Blender>echo %PYTHONPATH%
%PYTHONPATH%

just installed
VisualC++ Redist for VisualStudio2013 12.0.30501
vcredist_x64.exe
same result

Win7 64 bit is Version 6.1 (Build 7601: Service Pack 1)
Will check the runtime, VC2013 and PYTHON issue
Remember: reinstalling 2.71 work well

I had to update the driver with the last one from Intel.

I just tested 4 combinations:
no opengl32.dll and no --factory-startup
with opengl32.dll and no --factory-startup
no opengl32.dll and with --factory-startup
with opengl32.dll and with --factory-startup
all lead to the same error.

The trouble of attach is about a shot of the error.

I cannot find how to attach the shot of error.
