"Data Execution Prevention (DEP) is a security feature that can help prevent damage to your computer from viruses and other security threats. Harmful programs can try 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 can harm your programs and files.

"DEP can help protect your computer by monitoring your programs to make sure that they use system memory safely. If DEP notices a program on your computer using memory incorrectly, it closes the program and notifies you.
First, see if a DEP-compatible version of the program is available by visiting the software publisher's website. If the publisher has not released an updated, DEP-compatible version of the program, you can turn off DEP for the program that was closed. You will be able to use the program, but it might be vulnerable to an attack that could spread to your other programs and files.
