Berti007 Level 1 Level 1
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

    I am having the same problem with itunes and DEP. And i've done what you said her but just like the original post, "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." Any other ideas? This is driving me nuts!

    Unfortunately in Vista you can't turn off DEP for iTunes!!

    Please can someone help me out!

    If you can't turn off DEP in Vista for iTunes, permissions are not correct somewhere.
    I suggest searching Vista help sites for fixing this.

    Any idea on where to look? I've searched everywhere.

    I don't understand how, out of no where, after months and months of using iTunes on vista, it just randomly starts blocking it for no reason.

    Im using Vista Ultimate x64.

    Anyone have any ideas?

    Ok a re-install worked for me.

    Can anyone help me with this??

    I still can't even get iTunes to open let alone play songs - rendering my ipod useless!
  • Katrina S. Level 7 Level 7
    Have you tried creating another Windows Vista account, opening itunes, and dragging in a few songs into its library to see if things work OK in that account?


    Just trying to figure out if it is user-specific or system wide.
  • Berti007 Level 1 Level 1
    It's not user specific. I've tried it on other accounts and DEP closes iTunes each time. Please help me with this as I have an iPod here that I can't use!!

    Are you using 64 bit or 32 bit version of Vista?


    And are you still trying to Disable DEP?
  • Berti007 Level 1 Level 1
    It's 32 bit. I've tried disabling DEP however it says DEP must be enabled in order for iTunes to work - in essence, it won't allow me to add iTunes to the list of programmes I want DEP disabled for.

    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.

    Yes SP1 is installed. I have previously run the Apple and Quicktime clear up operations and removed all from my system then re-installed from scratch however that has not solved the problem.

    I am the administrator.

    Only other thing I can think of which may or may not bypass the DEP is disabling UAC for a bit to see if this allows more of a full access control and over rides what DEP was wanting to control.



    User access control can be turned on and off via the User Account Settings Panel
