Hello perhaps someone can help me.

Very recently, since a computer restart, on opening iTunes, I am confronted by error messages, and the program doesnt not start.

The error reads:

The application or DLL C:/Program Files\QuickTime\QTSystem\QuickTimeH264.qtx is not a valid Windows image. Please check this against your installation diskette.

Now this has never happened before. The error file has not been deleted, changed or modified. The error message varies between this files and various other files in the same folder. If I click "OK" on the error message, it appears again several times, usually 6 times, and am then attacked by multiple messages saying "iTunes has encountered an error and has to close" which is extremely irritating and frustrating. I can't imagine what I have done to cause this problem.

I searched for "bad image error" on these forums. Someone else seemed to have had a problem with a "Bad Image Error" but it seemed to be a problem with directX rather than quicktime.

Any assistance would be gratefully received. I have tried restarting multiple times and have tried to reinstalling iTunes to no effect.

Thank you

Windows XP

    yeah, it's a bit unusual to be getting one of those messages citing a QuickTime file.

    so we're proceeding in a general principles troubleshooting mode here.

    plausibly, there's a damaged file or files on your hard drive. so perhaps let's try running a chkdsk over your C Drive:

    does the chkdsk find/repair any damage? if so, do you still get the message afterwards?

    Thanks for replying

    No, no errors found.

    If it helps, opening QT is met with an almost identical error, I also get a visual libray C++ error.

    Completely stumped!

    okay. let's see if we can swap out your existing QuickTime.

    head into your Add/Remove programs. uninstall QuickTime.

    Next, we’ll manually remove any leftover program files and folders.

    1. On the Start menu, click My Computer (or double-click My Computer on the Desktop).

    2. In My Computer, open Local Disk.

    3. Open Program Files.

    4. Right-click on the QuickTime folder and click Delete from the shortcut menu.

    5. Navigate to C:\Windows\system32\.

    6. Remove the files QuickTime.qts and QuicktimeVR.qtx.

    7. Restart your computer.

    next, we'll get a fresh copy of QuickTime into your PC by doing a repair install of itunes.

    switch off antivirus and antispyware applications prior to the repair install.

    go into Add/Remove and select itunes. click "Change" and then click "Repair".

    if the repair install goes through okay, restart the PC and try launching itunes again. does it launch properly now?
