System Information

Windows 7 SP 1, x64, Intel HD Graphics 4400 with i5-4200U, no external graphics.
No previous history of installing or running Blender.

Blender Version
Broken: 2.75a(Released July 8, 20150

Short description of error
I downloaded the portable version of Blender 2.75a to my laptop.
I extracted it to a folder, and ran blender.exe. A cmd.exe window opened and immediately disappeared.
I couldn't see any error messages, and the process was already dead.

I opened a command prompt, moved to the directory, and ran blender.exe.
The program immediately died again, leaving an error message - "Error : EXCEPTION_INT_DIVIDE_BY_ZERO".
I removed the portable version and used the installer, but the result was same.
When I run it with debug mode(blender.exe -d), this comes up:

Switching to fully guarded memory allocator.
Blender 2.75 (sub 0)

Error: EXCEPTION_INT_DIVIDE_BY_ZERO

I installed Visual C++ 2013 Redistributable Package linked in the download page. The error remains still.
I ran it with Administrator privilege, but it didn't work. (In fact, my cmd.exe runs as Administrator mode.)
I couldn't find any log(it makes OGLdpf.log, which is empty, and there is a folder named blender_aXXXXX, which is empty).

There is no special character in the path.
I tried D:\ProgFiles\Blender, D:\ProgFiles\Blender Foundation\Blender, and C:\Blender, but neither worked.

I saw a Python binary inside Blender's folder.
I wondered if previous installed Python would cause any trouble, so I renamed the root folder of previously installed ones(in order to hide them) and ran Blender. Not worked.

I googled with keyword EXCEPTION_INT_DIVIDE_BY_ZERO or Blender won't start, but I couldn't find any similar bugs.
I wonder if it's my computer's fault - which would be embarrassing(as it means this is not reproducible)...
Please tell me if you need more information. Thank you.

This isn't really reproducible. Things to try:

Make sure you've got latest video drivers installed (it worth going directly to Intel's download center because your laptop manufacturer might have out-of-date drivers).
Make sure your operation system is all up to date.
If that doesn't help, download opengl32.dll from ftp://ftp.blender.org/sergey/softwaregl/ put it next to blender.exe and see if it has any affect on the crash. This will switch blender to fully software OpenGL mode which would help us eliminate possible driver issues.

I tried them, but it didn't work.

Scrolling through Blender's command line options, I found this:

--disable-crash-handler
Disable the crash handler

I googled and found a commit where 'EXCEPTION_INT_DIVIDE_BY_ZERO' line was added . The message was a crash handler; when Blender encounters critical error, it would report an error instead of crashing.
So I ran Blender with crash handler disabled, look what I saw:

imgur link
It's just a Korean-labeled window of 'XX has stopped working'. There I saw which DLL file caused the problem.
That Wintab32.dll, was in my C:\Windows\System32, but I dont' know why it's there. It's not signed, and I don't understand why Blender hooks it.
(Looking at 'tab', it might be related to pen tablets like those from Wacom; I used to use one)

Anyway, renaming Wintab32.dll to something other immediately solved the problem. Thank you.

The error seems to be unrelated to Blender. I don't know what to do with this thread now. Can someone teach me?

It is not really a fix, but at the same time it doesn't seem to be issue with blender.

wintab32.dll is a part of tablet driver, you might want to try updating it and see if it solves the crash and lets you still to use tablet.
