Data Execution Prevention (DEP) - Can't open iTunes!! help!

As above, everytime I try and open iTunes a window appears saying DEP has closed the programme to prevent my computer being damaged. I've run all the clearing exercises of iTunes and Quicktime and re-installed it but to no avail. This has only happened after I upgraded iTunes recently. I am using Vista and I have tried allowing iTunes in the DEP control panel however it says DEP must be working in order to execute this programme.

Please can someone help me out!! I don't want to have to system restore!

HP Pavilion, Windows Vista

ive had the same problem with DEP closing one of my programs. all you need to do is delete itunes from that list. to do this Click the start button, go to control panel click performance and maintenance then click system. click the advanced tab and under performance click settings. click the Data Execution Prevention tab. you can either change it to turn on for all programs and services or just for those you have listed. click just for those you have listed. then delete itunes from that list. you can also place a check next to itunes and click ok to turn off for this program. exit out and then restart your computer. you should be able to open itunes then

Have you downloaded and installed Windows Vista Service Pack 1 yet?



This may assist you with that you are running into. If you have already done this let me know. Could still potentially be something going on with the Apple Software.


If this is the case the link below describes how to fully clean out Apple Software. Possible file that belongs to Apple may of become corrupted and thus causing iTunes not to launch Properly.


But before you check the article out. Have you right clicked on the iTunes Application and chose Run as Administrator?

You can also right click on the iTunes App, Select Properties, and select Compatibility Mode - And make sure that is not turned on and set for something else. As this could potentially be running in a different mode.
