Data Execution Prevention (DEP) is a security feature that can help prevent damage to your computer from viruses and other security threats. Harmful programs cmay 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:
- Open an xcpt*.txt file with Notepad or your favorite text editor.
- Scroll down to the [Exception info] section.
- 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
If you choose to protect all programs, you can still disable DEP for individual programs. 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 you change any DEP settings.
