System Information
Windows 7, Nvidia Geforce GTX 660M

Blender Version
2.7.1.0

Short description of error

When I click on Blender the program doesn't start.

I get an error saying "Blender has stopped working" and the following is in problem details:

"Problem signature:

I realize others have reported similar problems but I haven't found a good solution on the forums. I tried re-downloading the Microsoft C++ redistributable (MSVCR120.dll) and copying it into the blender install folder but this doesn't help.

Any help is appreciated!

Thanks so much!

Do you have Service Pack 1 installed for Windows?

It could be opengl related issue. Please:

Try installing latest video drivers
If that doesn't help try download opengl32.dll from ftp://ftp.blender.org/sergey/softwaregl/ and put it next to blender.exe. This will switch Blender to use fully software opengl eliminating possible interference with bugs in there.

Hi Juicyfruit, FYI I haven't experienced such an issue with my local setup:

Windows 7 Pro w/SP1 64 bits + GTX 360M 1GB VRAM; Blender 2.71.0 64bit (Hash: 9337574; blender-2.71-windows64.zip)

as well as with the latest build: Blender 2.71.3 64bit (Hash: a90e49e; blender-2.71-a90e49e-win64.zip)

I have administrator privileges both locally and on the network domain. Blender is always run from the unzipped distribution (I never install it).

Even if I haven't experienced this specific issue I am herewith attaching the results of the dependencywalker analysis on a fresh unzip of the latest buildbot release (a90e49e) including the results after profiling, in case they might help:

@Harvester thx, The one I really want is from anyone who can reproduce the issue. But thanks for taking the effort :)

Could you maybe also try and run the 32 bit build from the buildbot ?

In some simples PC without graphics card, Blender don't start. My computer is the case.
I always shutdown directX in "properties of video" ---> Hardware acceleration. (I slide the bar to minimum)
Only so blender start.

Hi Cristiano, I'm not sure it may be related to your comment but as stated in the minimum system requirements to run Blender
(http://www.blender.org/download/requirements/) it's at least required to have an OpenGL-compatible graphics card with 256 MB RAM.

I was on a windows 7 64-bit till date.
I now installed Windows 8.1.

I have some weird news :p

Blender 2.71-win64 does not crash on launch but now the performance is really really slow.
The default scene with the cube lags as I rotate my view. Tried a few of my work files. All lag very heavily.
The same with 2.71-2ec0077-win64.

2.71-d9f3925-win64 and 2.71-e13d6e2-win64 (which previously would crash on launch) operate perfectly without lag.
I did not change any hardware.
I have 8GB RAM, GTX 560 ti, i7-4770k

Hope this helps:)

@Flippy yes could be. but this ticket might also be a lot of separate non connected issues all resulting in blender not starting

@Sergey @ThomasDinges I think the way we find our re-distributable dlls' is also very very brittle, we should use something like the env to copy them from the actual compiler used rather then relying on some redist directory.

From @Flippy comment on merged report:

Something wrong with Python?

Indeed, looks like Blender tries to use some system python (2.7) instead of own embedded one (py 3.4)! @Sergey, @MartijnBerger, thoughts?

@Flippy: btw, instead of trying to catch Blender’s console, you can just run it from a real Windows command line, which will stay open after Blender crashes ;)

EDIT: meh, sorry, did not saw you cross-posted your comment in both threads! :/

This issue not contains at least 3 distinct problems.

The following are NOT considered a bug:

Not having proper OpenGL drivers
Trying to run blender with python 2.7 libraries. ( This will not work and is not intended to work ever )
Not having a supported versions of windows. ( For windows 7 please update to service pack 1, for Vista update update update.. but it should work after you fully updated )

The buildbot releases up until yesterday had an issue which I solved so please retest.

I was having this same issue on Windows 8 x64. I also had python 2.7.4 installed. Blender was trying to use python 2.7.4 instead of the local 3.4 dll it is packed with. I worked around the issue by creating a batch file to temporarily redirect the PYTHONPATH. The batch contents follow:

setlocal
set PYTHONPATH="DIRECTORYWITHBLENDER"
start "DIRECTORYWITHBLENDER" blender.exe

Run the bat file and all is well.

I Know this has been closed/Archived.

I came back to this today though on curiosity (I had been using an older blender version... but really wanted to upgrade for the newer sculpting features).

It turns out that even though Blender throws a C++ runtime error it -IS- truly in the python path.

I had python 2.7 on my computer and going into system variables and changing the PYTHONPATH to be located in my blender folder fixed the issue.

I HAVE THE SOLUTION

It worked for me.

Download the newest python version.
Locate you python and you blender path.

3.Go to YOUBLENDERPATH/YOURBLENDERVERSION.

4.There should be a folder called python.

Make a copy of that folder.
Copy you WHOLE Python Folder(That you have downloaded/installed) into the YOUBLENDERPATH/YOURBLENDERVERSION folder.
Blender should work now.

In my case info from Windows was "same" (dll file, and ver. 12.0.21005.1)

It disappear without any steps after install higher version of '13 redistributable form MS.

@Biowulf, @domeylp, @modilion could you check that out on 2.76b without any changes in blender3d environment (entire python distro copying, changing paths?)

Best regards!

PS I could start 2.60 and 2.70 but any higher before that step. Tested on clean Win 7 Pro installation, after upgrades (SP1) and with no python (package, installed instantion... I hope you understand) installed. Intel i7 (4700HQ), nVidia GT 740M, SSD + HDD, 16GB RAM (low CL ;) )

In my case info from Windows was "same" (dll file, and ver. 12.0.21005.1) It disappear without any steps after install *higher* version of '13 redistributable form MS. @Biowulf, @domeylp, @modilion could you check that out on 2.76b without any changes in blender3d environment (entire python distro copying, changing paths?)

Please do not reopen such old reports that way, there’s quite little chance the issue would be the same actually. And it’s totally confusing to follow what’s the issue for who.

Please open a new report (with all required info) - in which you can link to that one if you think it's meaningful.
