Looks like no one’s replied in a while. To start the conversation again, simply
ask a new question.
I'm able to remove/uninstall and re-install itunes and all the components, i've completely cleared all temporary files and installed several times. Install process works no problems it just wont actually open the software.
I have also downloaded the.NET framework and repaired it.
The computer is telling me there is a problem with the data execution prevention, i have tried to manually over-ride it with no success.
In this context (launching itunes), DEP errors can indicate that some other program (other than QuickTime itself) has sprayed old versions of QuickTime componentry into unorthodox locations on the PC.
Although the error 7 is most commonly associated with Apple Application Support or .NET framework problems, it can also be associated with QuickTime trouble ... so that's consistent with the old, misplaced QuickTime componentry troubles as well.
So I think we'd better check on that possibility.
You'll need to check some view settings on the PC first.
1. From the Start menu, click Open.
2. In the Organize menu, click Folder and Search Options.
3. Click the View tab.
4. 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. 5. Click OK.
Now go "Start > Computer".
In Computer, open "Local Disk C:" or whichever drive your operating system is installed on.
Open the "Windows" folder.
*If you have a 32-bit Vista,* open the "System32" folder.
*If you have a 64-bit Vista,* open the "SysWOW64" folder.
What files or folders can you see in there with
QuickTime in the file or folder name? (In a standard installation of QuickTime, you should see precisely two
files ... QuickTime.qts and QuickTimeVR.qtx ... and no QuickTime
folders whatsoever.)
Hmmmmm ... doublechecking something, Cherry. Do you have a 64-bit Vista?
The complete reinstall instructions wha gave you should work fine for an Apple Application Support problem on a 32-bit Vista. But they aren't quite accurate for 64-bit systems yet (although they're better than they used to be), and could leave behind damaged AAS program files on a 64-bit system after an AAS uninstall that cause problems even after AAS is reinstalled.
If you've got a 64-bit Vista, we'll try the reinstall again with tweaked instructions for the "Verify iTunes and related components are completely uninstalled" section that should catch any lurking AAS program files.
No problem, I was thinking about pointing to one of your posts anyways. 🙂
Cherry, assuming the computer information is for this PC, you could try removing and then reinstalling the .NET Framework again. This Miscrosoft article:
http://support.microsoft.com/kb/908077 should walk you through the process.
If the issue persists, we may need installer or event logs.
