Hello,

I am new to Itunes and have read several topics on this error, that was supposedly solved in the newer versions.

I installed itunes yesterday and managed to get my music onto and that was fine until i restarted my computer, at which point i got the DEP message at which point my computer froze after trying several times to solve it.

upon restart my harddisk was not recognised and (not responding). I recived this screen, and then after restarting through Safe mode then recieved a windows crashed message saying that new software had caused this. ( the blue screen).

So i managed to get onto windows (6 hrs later through many start-up system repairs). Unistalled Itunes, quicktimes etc.

Tried through several threads about deleting quicktime, installing newest version over itunes and so on and so forth without any success.. Just the common DEP message and sometimes computer crash. Which wont allow me to start windows!!

It has become very frustrating and extremely time consuming, at which point i have back everything up now and cleaned entire computer to avoid another of these crashes.

I have Windows 32 Vista, Dell Inspirion 1525, 4gb ram, intel core duo 2.00ghz which i was told upon purchasing ipod that was sufficient.

Is the problem APPLE or DELL- DELL have said its a software problem btw?

Dell Inspirion 1525, Windows Vista

    Try installing the latest Quicktime and itunes from itunes web page. I tried everything else and nothing worked. This fixed it for me.Good luck.

    I have the same problem - basically I have to go to a vista restore point prior to august 2, 2009, then everything works fine.

    Of course, I haven't turned windows updates off, so then windows goes and puts back everything the restore point removed, and it breaks until I invoke the restore point again. This makes it pretty obvious to me that there's something in a Windows update that happened after 8/2 that is incompatible with iTunes.

    On my system, I can neither start ITunes nor install/reinstall this until I go through this restore point procedure...

    That's interesting about the Window update. It's not the first time a microsoft update has broken things...A few years ago, there was a really bad update to time zones that rendered hundreds of programs useless. Microsoft came out with an update pretty quickly, but you had to know which date you had DL'd the update as to whether it was fixed or not, because microsoft did not rename it.


    I am currently getting errors fom another program (not itunes) due to a recent .NET update. I'm going to take out the windows update and downooad a fresh copy of it.

    Hi, I just got this problem solved. Hope it helps.
    You don't have to turn off DEP or reinstall any program.
    The only thing you need to do is associate your Quicktime files ONLY to QuickTime player.
    When you open QuickTime it will automatically pop up a window to ask you if you want to fix file association. The answer is positive of course.
    If it still doesn't work maybe you could uninstall some codec / media players which associate with QuickTime files.

    If Quicktime doesn't work, then iTunes can not work.

    Have you installed any of the following:
    ACE & K-Lite mega codecs package, QT alternative, Storm codec, WinAVI video converter, Mpcstar, (possibly starcodec pack, 3ivx, Xilisoft converter)

    If so uninstall them, they are know to cause problems with QUickitme.

    Then/otherwise download the version of Quickime without iTunes:
    http://www.apple.com/quicktime/download/win.html

    Now Remove Quicktime using the method for Quicktime in this article (just Quicktime):
    XP
    http://support.apple.com/kb/HT1925

    Vista
    http://support.apple.com/kb/HT1923

    When you come to your C:\Windows\system32\ folder you can delete any file or folder with Quicktime in the name.

    Restart you computer
    Install the stand alone Quicktime and check if it starts.

    If it does you are in a position to find out if iTunes is OK.
