🙂 S'okay, no need to apologise.

That DEP error suggests a slightly unusual possibility with an error 7 that we'd better follow up on.

Can you check to see if your QuickTime Player is currently launching, please? Or do you get an error then too? (DEP errors can indicate that some application has stashed old quicktime componentry in your system files, although that more commonly produces an "iTunes has stopped working" than an error 7. Either way, if the QuickTime Player has stopped working too, we'll go hunting for the out-of-date QuickTime componentry.)

QuickTime will not open either. You get the same error message and the 'data protection' crap.


Yeah, that most definitely sounds like old, misplaced QuickTime componentry. (Especially if you're getting a "QuickTime has stopped working".)

So we'll go looking for the older QuickTime componentry in the most common locations for it to be stashed.

First we'll need to change some view settings.

In your Start menu, open Computer.
In your Organise menu, select Folder Options.
In the View tab, make sure that "Show hidden files and folders" is selected, and Hide extensions for known file types is unchecked.
Click OK.

Now in Computer, open your C:\ drive (or whichever drive you have your operating system installed on).
Open the "Windows" folder.
*If you have a 32-bit version of Windows,* open the "System32" folder.
*If you have a 64-bit version of Windows,* open the "SysWOW64" folder.

What files and folders can you see in there with QuickTime in the title? (In a standard installation of Quicktime you should be seeing precisely two files ... QuickTime.qts and QuickTimeVR.qtx ... and no QuickTime folders whatsoever.)

Okay ... just in case, have a check in your system32, and also \Windows\ too. (Usually a 32-bit app will drop stuff in the SYSWOW64 folder. But some of the apps in question that do this are pretty old and/or scruffy ... so they may be getting horribly confused by the Windows 32 on Windows 64 technology and be dropping componentry in really strange places.)

in Windows have the 2 you mention AND Quick Time Object?? In Sys32 have found quick.ime??


leave the two files I mentioned and the quick.ime where they are. Drag the QuickTime Object out onto your desktop.

Now try launching itunes and the quicktime player again. Do they launch properly this time?
