Blender 2.8 doesn't start. I'm on windows 32 bit, Lenovo IdeaPad miix 300, one of these old 2 in 1 tablets.
With Intel graphics, Intel atom and 2gb ram, it could be that it doesn't meet the requirements. It supports up to OpenGL 4.0 so it shouldn't be a problem.
2.79 and the 2.79 daily builds work fine ("fine")
Either the requirement of OpenGL 3.3 ist false or it's a bug. I've tried yesterday's and today's daily 2.8 build bot build, both show up a terminal without contents for a couple seconds and then close, no error message whatsoever. 2.79 has been proven surprisingly useful on such a weak tablet and it'd be cool to get 2.8 on there since it should technically be supported anyway.

Generic advice:
Run blender from a terminal window so you can see any error messages.
Use updated graphics driver - preferably from your card's manufacturer.

Please mention what version of Windows and your specific graphics card.

I did run it from terminal. No output there, just a blank line and then it quits.
blender.exe --help and --version works, so at least it's not completely broken.
I'm on windows 10 home 1803 32 bit
The graphics is intel integrated.
Here is the output of dxdiag, maybe that can help. There's something about blender crashes in there too.

There should be an output from the terminal...

Open Command prompt:

Drag and drop blender.exe and add

--debug

to the end hit enter.

It should look something like this (not the exact filepath):

"C:\Program Files\Blender Foundation\Blender2.8testing\blender.exe" --debug

If that doesn't work then here's a general (paste) list of things to check/do:

Please:

Give us your exact Blender, OS and GPU (including drivers) versions, as requested in the template!

Ensure both your OS and drivers are fully up-to-date (and use official GPU drivers, not those provided by windows or tablet/laptop maker or open source ones in linux distributions).
** If your GPU driver is already to latest version, try down-grading to a few previous versions (sometimes newest versions introduce bugs…).

For Windows 7, at least service pack 1 is mandatory, please ensure it is installed on your machine.

Try to disable any running antivirus.

Try to disable any custom input device (de-install their drivers even), like some graphic tablets, some 3D mice, etc.

Try the latest build from our buildbot.

Try to start Blender in factory settings (--factory-startup commandline option) (this will ensure whether this is a userpref or addon issue or not).

Try to tweak your GPU driver settings (e.g. try different values between 'performance' and 'quality' if you have such slider, etc.).

Launch Blender from the command line with -d option and attach as text file here any error printed out in the console (do not paste it directly in comment).

Launch Blender from the command line with --debug-cycles option and attach as text file here any error printed out in the console (do not paste it directly in comment).

Launch Blender from the command line with --debug-gpu option and attach as text file here any error printed out in the console (do not paste it directly in comment).

There should be an output from the terminal... Open Command prompt: Drag and drop blender.exe and add ``` --debug ``` to the end hit enter.

It started with --debug enabled for some strange reason.

debug-gpu and so on did nothing.
So I tried deleting the 2.8 prefs from the appdata. Didn't work.
So I went all out and deleted the entire blenderfoundation folder including 2.79 prefs although the 2.8 prefs were already gone.
And it started without issues. Could there be some permission issues? I thought every app could write to the appdata.
But here's another issue: The viewport performance and responsiveness was about half of what 2.79 delivers. Is the new viewport just that much slower?! Here is the output of blender.exe -d

I had similar problem on windows 10 64bit, on both 64 and 32bit builds. After deleting userpref.blend file blender started, but it keep failing on exit and load file.

Here is output of start blender then immediately exit:

@paperbenni, can you attach the output of Help > System Info in Blender 2.79?

It's not clear to me that this graphics card does fully support OpenGL 3.3. When it was released it only supported only 3.2, while OpenGL was already at 4.4 at the time. Maybe it got added later in the driver, but it's odd.

@iss, that seems like a different bug.

There it is.
Opengl extensions viewer also shows opengl 4.0

I really hope it is unable to use OpenGL for some reason, otherwise this is deeply concerning. Should I open another bug report or is 2.8 just half as fast as 2.79?!

Blender 2.8 is optimized for modern GPUs, this system will likely soon be below our minimum requirements. 32 bit support will likely be dropped soon as well. So we're unlikely to invest time optimizing for this system, and would not handle poor performance on this system as a bug.

I missed that removing the old settings seems to solve the crash. So I'm not sure there is anything remaining here that we can fix.
