Does Quicktime work normally? Itunes cannot work if Quicktime doesn't.
Problems with CODECs are a common cause of DEP errors in Quicktime appearing immediately after an upgrade.
If Quicktime doesn't work, and you installed any of teh 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 download the version of Quickime without iTunes:
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.
