DEP messages can be caused by old QuickTime componentry being stashed (by other programs than iTunes or QuickTime) in unorthodox places on a PC. On a 64-bit system, the best place to start looking for that is in the sysWOW64 folder.
From the Start menu, click Open.
In the Organize menu, click Folder and Search Options.
Click the View tab.
In the "Advanced settings" pane under "Hidden files and folders" make sure that the "Show hidden files and folders" option is selected and the "Hide extensions for known file types" option is unchecked.
Now open your C:\Windows\SysWOW64\ directory.
What files or folders can you see in there with QuickTime in the file or folder name?
(In a normal QuickTime installation there should be precisely two QuickTime files ... QuickTime.qts and QuickTimeVR.qtx ... and no QuickTime folders whatsoever.)
Hi, I've just upgraded my system from Vista home Premium to Windows 7 Home Premium. I did this so I could use my iPhone / iTunes thinking it was the vista program. I still cannot use iTunes with windows 7 installed. It just will not open. I did a troubleshoot compatability test and it comes up using windows xp service pack 2. I've tried uninstalling iTunes and reinstalling the program and it still wont work. Any help would be greatly appreciated....
Hi, I just had a look on the file you suggested and the following files are present:- CFCharacterSetBitmaps.bitmap CFUniCharPropertyDatabase.data
CFUnicodeData-B.mapping CFUnicodeData-L.mapping QuickTime3GPP.qtx
QuickTimeAuthoring.qtx QuickTimeEssenials.qtx QuickTimeImage.qtx
QuickTimeInternetExtras.qtx QuickTimeMPEG.qtx QuickTimeMPEG4.qtx
QuickTimeStreaming.qtx QuickTimeStreamingAuthoring.qtx QuickTimeStreamingExtras.qtx QuickTimeWebHelper.qtx
this is the only files in this location. Do I delete all of them?
I've just did an upgrade to windows 7 and still cannot use iTunes.
I have now solved this problem. I uninstalled itunes and reinstalled it about 4 times. I even upgraded my system to windows 7 and the whole time Quick time was not uninstalled properly.
Uninstall itunes and all associated applications. restart computer
Go to start menu and in search programs and file type in program files(86x) click on the link and see if quick time is there if it is delete it and exit.
Go back to start menu and in search programs and file type in C:\windows\SysWOW64, click on this file and see if quick time is there if it is delete it. restart your computer
I did the above and now my itunes works for my iphone / ipod.
