The Sims 3 Launcher runs executable with the highest version number so you only have to add the executable you are using to the DEP list.  For example, if you have The Sims 3, The Sims 3: World Adventures, and The Sims 3: Ambitions installed, you only have to add the executable belonging to Ambitions to the list (TS3EP02.exe).  It is not recommended to add more executables to the list than you have to in order to prevent crashes.  The full list of executables are below.

Overview

Data Execution Prevention (DEP) is a security feature in Microsoft Windows (an implementation of the NX bit technology) that can help prevent damage to your computer from viruses and other security threats. Harmful programs may attempt to attack Windows by attempting to run (also known as execute) code from system memory locations reserved for Windows and other authorized programs. These types of attacks may inflict serious harm to your computer (operating system, programs, and data).

DEP protects your computer by forbidding access to memory not reserved by the running application. If the processor notices a program on your computer using memory incorrectly, it halts exectuion (terminates the application).


Diagnosing DEP Crashes

The Sims 3 produces exception (xcpt*.txt and xcpt*.mdmp) files in the user's My Documents directory when it crashes. To determine if the crash was caused by DEP:

  1. Open an xcpt*.txt file with Notepad or your favorite text editor.
  2. Scroll down to the [Exception info] section.
  3. Behind address:, does it have <unknown module>? If yes, DEP caused the crash. If no, something else caused the crash.

Applications That Can Diagnose DEP Crashes


Change DEP Settings

Note: If you change this setting to monitor all programs, you will have to add each program that DEP closes down to the exception list.

If you suspect that a program does not run correctly when DEP is enabled, check for a DEP-compatible version of the program or an update from the software publisher before changing any DEP settings.
