System Information
Win 7 64bit, 6GB RAM
ATI Mobility Radeon HD 5650 (3703 MB RAM)
HP Pavilion laptop

Blender Version
Broken: 2.78b hash 3c04373 Win64bit
Worked: 2.78a

Crashes on launch of blender.exe (EXCEPTION_ACCESS_VIOLATION)

Exact steps for others to reproduce the error
Dbl click on blender.exe desktop icon, program starts, displays cmd window, then crashes (never see UI/splash).

I tried using --factory-startup, and the opengl32.dll-in-blender-folder-trick, no luck. I suspect its a video driver problem - I can't get recent drivers for my older laptop (2011?). Using 2.78a version mostly works - it starts up and I can create new .blend files - the only thing that didn't work with that version is it couldn't load your demo blend files (from your website), nor could I display the "System" tab in "User Pref" - both would result in a crash. clinfo.exe (from ATI) also crashes on load.

From the cmd line:
blender.exe --factory-startup --debug-cycles
AL lib: (EE) UpdateDeviceParams: Failed to set 44100hz, got 48000hz instead

Broken: (example: 2.69.7 4b206af, see splash screen)
Worked: (optional)

I was looking to upgrade my blender using choco packages. After upgrading to 2.78 I get
Error: EXCEPTION_ACCESS_VIOLATION

I tried uninstalling and reinstalling, strange the app still is on disk and even the downloaded msi it seems.

I would like to understand and help with resolution of this bug if possible.
Thanks.

If a package uninstall is failing and/or you've already uninstalled the
software outside of Chocolatey, you can attempt to run the command
with -n to skip running a chocolateyUninstall script, additionally
adding --skip-autouninstaller to skip an attempt to automatically
remove system-installed software. This will only remove the packaging
files and not things like software installed to Programs and Features.

If a package is failing because it is a dependency of another package
or packages, then you may first need to consider if it needs removed
as it is typically installed as a dependency for a reason. If you
decide that you still want to remove it, head into
$env:ChocolateyInstall\lib and find the package folder you want
removed. Then delete the folder for the package. This option should
only be used as a last resort.

@davehorner Seriously! Please:

Do not add comment about totally different issues to another report, create your own!
Do not paste walls of text like that directly in reports/comments, such reports must be attached as text files instead.
Do not report bugs about unofficial builds and/or old versions, always check with latest release and current master builds before reporting.
So considering your case cleared.

@michael2000

clinfo.exe (from ATI) also crashes on load.

That means you have a serious GPU driver issue, we cannot really help here, if even basic diagnostic tool from very vendor of the GPU crashes…

Not being able to update the drivers is also not good news, but it’s a bit strange that it still crashes with software OpenGL. I would infer from your crash report from console that the issue is with OpenCL initialization, which could be perfectly explained by the old drivers.

There is some way to disable OpenCL checks at startup with envvar iirc, @Sergey should know about it?

In the mean while, please try the latest build from our buildbot, and try starting blender from command line that way: CYCLES_OPENCL_TEST=true /path/to/blender

In order to disable OpenCL completely you should be using CYCLES_OPENCL_TEST=NONE environment variable.

Setting CYCLES_OPENCL_TEST=NONE fixed the problem. Can also now access the System tab in user preferences and load your demo blend files without crashing. Thanks for the quick help!

With this OPENCL environment variable set, will it prevent any features from working?

You won’t be able to use OpenCL for GPU rendering with Cycles - which you probably already cannot do anyway.

I’ll close the report for now, OpenCL is rather touchy currently, and definitively needs the ultimate latest drivers (and usually very recent hardware too) to have a hope of it working…

PS: do not, absolutely not, use the GPU drivers featured by your laptop vendor, those are never really maintained and nearly always way too old. Try to download them directly from AMD website, it’s the only way to get latest one, hopefully this will fix your issue.
