For others who find this thread - I found help on the #unity3d channel on Freenode IRC.

The problem was that I had Data Execution Prevention (DEP) turned on, and had not added the Unity editor ‘unity.exe’ as an exception.

I corrected the problem (Windows 7) by going to Control Panel → System and Security → System → Advanced system settings → Advanced (tab) → Performance Settings → Data Execution Prevention (tab), clicking “Add…”, then browsing to “C:\Program Files (x86)\Unity\Editor\Unity.exe”.

Strangely, I remember older versions of Windows notifying you when DEP was the reason for a program being shut down - On Windows 7 the Unity program was just failing silently and generating crash reports (as posted above).

Is there a bug / feature-request to have the Unity editor properly mark its regions of memory (per Data Execution Prevention - Win32 apps | Microsoft Learn ) to not trigger this?

I had the same problem after new setting up of my system and the solution worked. thanks.

Wonderful Solution! thnx!

I am using Unity 3.3.0 in Windows XP.

Here’s the path of DEP on XP:

Start Menu > Control Panel > System > Advanced > Settings > Data Execution Prevention >

  1. Click on Turn on DEP for all programs and services except those I select:

  2. Uncheck Unity Editor (if not there, click on Add button to add it to the list)

  3. Click Ok, and restart windows
