I've installed the free Zone Alarm download. The download appears to be successful, then when the program tries to open Windows informs me that Zone Alarm has stopped working because the Data Execution Prevention is stopping it. I followed the instructions from someone else's thread, that is, uninstalling and reinstalling it, and I also followed what Windows said about allowing a program through the DEP, but each time it failed. I need ZoneAlarm to start running soon. Please help.
