I just installed Blender, but when I try to start it, the command prompt comes up with "Error: Exception_Access_Violation" and then closes (and Blender never starts of course). How do I fix this? I tried running as administrator and that doesn't help either.
I want to answer so that anyone with my particular situation might benefit ... I had this same frustrating problem with WIN 7, and a Intel HD graphics (which supports only OpenGL 2.1) ... I tried some suggestions which didn't work (though I needed the 2013 C++ library anyway, a link to this is given at the Blender site just below the Blender download links--I had only 2010) then I simply updated the graphics driver from a 2010 version to the 2012 version . and that did it. Actually I was surprised it did, but it did.
Read also that some other people had to go back to an older driver instead.
At any rate 2.77 can at least run with a Intel HD graphics, I am proof.
By the way I used an Intel utility called Intel driver update Utility to find the right driver. The screen went black after the driver was installed, and I feared the worst, but after restarting things seemed ok, the driver was installed and even Blender worked! Darkest before the dawn or something. Assuming all is well..
Oh last detail which probably doesn't matter) I didn't install Blender, I unzipped the zip file and ran it straight..
I googled this and found this bug report:
You need to delete ALL versions of blender (you will need admin privileges), then reinstall the latest version.
"I was also experiencing this bug on with version 2.76 windows 10 like Will Tice. Like Will I had followed all the instructions above to no avail. I decided to try the older 2.73 version of blender and was uninstalling 2.76 when I noticed there were left over files from version 2.69 from windows 8. After thoroughly cleaning out all blender files and reinstalling 2.76 I'm having no issues. Checking for and removing previous versions of blender may help with this issue."
"I had the same problem but noticed I had a 32bit 2.6x version around together with the 2.76 I had just installed. Getting rid of the two of them and reinstalling just the 64bit 2.76 got rid of the problem."
"I'm using Windows 10 and had this issue. Uninstalling both versions of blender and reinstalling blender-2.76b-windows64.msi fixed it."
Another potential problem could be your drivers/video card, although I highly doubt it:
Downgrading from 2.79 to 2.78 worked for me aswell, until I activated cycles render, then it crashed.
I had to upgrade my intel graphics driver, too Intel Support. The thing was, that my intel graphics were disabled (It seems that many motherboards do this automatically, when a graphic card is plugged in). So I had to activate onboard graphics in the bios first, before I could update the intel graphic driver.
Now everything is fine again.
Had the same issue. Tried updating graphics driver, removing all of the old blender installs, as well as reinstalling newest blender version only. None of them worked for me.
Downgraded blender from 2.79 to 2.78, and it worked again!
Maybe this helps someone out there.
i just downloaded opengl32.dll from this web site ftp://ftp.blender.org/sergey/softwaregl
i hope that's well help some one because it worked for me.
It turns out Windows Update doesn't do anything to update the graphics driver. Go to Intel's support site, look for your graphics card (in my case Intel HD Graphics 620), and manually install the graphics driver. This solved the problem for me.
