I don't have a solution for this, but does your Quicktime work normally?
I have seen a suggestion that DEP errors can be caused by misbehaving codecs.
Do you have any of the following:
ACE & K-Lite mega codecs package, QT alternative, Storm codec, WinAVI video converter, Mpcstar, (possibly starcodec pack, 3ivx)
Apart from Startcodec, I do not know that these cause DEP errors but they can cause Qucktime problems.
I have seen one report that uninstalling starcodec and reinstalling QUicktime cured a DEP error problem.
I would uninstall all of those - at least until you get Quicktime going.
Then download the version of Quickime without iTunes (it is not the default):
Now Remove Quicktime using the method for Quicktime in this article (just Quicktime):
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.
