Internet Explorer 8 includes a security feature that shuts down misbehaving applications before they can harm your system.
This capability, known as Data Execution Prevention (DEP), runs by default when IE 8 is installed on XP SP3 and Vista SP1 or later, but it may not always be clear to you why DEP has put the brakes on one of your PC’s applications.
DEP is the best reason I know for updating to Internet Explorer 8 and Vista SP1. For many years, Microsoft has included DEP which is also called No-Execute (NX) only in parts of Windows. For example, DEP is available in IE 7 but is off by default to avoid conflicts with old, incompatible programs.
DEP is now a key part of Vista and Internet Explorer 8. When I try to install older software on newer machines, I must configure Data Execution Prevention to allow the software installer to run with DEP disabled.
To open the Data Execution Prevention dialog in XP, open Control Panel, choose System, and then select the Advanced tab. Click the Settings button in the Performance section and select the Data Execution Prevention tab. In Vista, choose Performance Information and Tools, click Advanced Tools in the left pane, select Adjust the appearance and performance of Windows, and click the Data Execution Prevention tab.

Jason Data Execution Prevention (DEP) is a security feature built into Windows Vista that helps prevent damage from viruses and other security threats by monitoring your programs to make sure they use system memory safely.
If you’re trying to use a program that’s being blocked from running by DEP this guide might be able to help.
Warning: Make sure the program being blocked is not a virus. Another reason for DEP blocking software is because it’s been written so poorly it would make your system unstable. Use this guide at your own risk.
Turn Off DEP for an Individual Program
