    If you go to Vista's Start Menu, and click on Help and Support (on the right
    side of the menu), do you see images at the top of the Help and Support
    window, or "red x's"?

    I've had a similar problem: after uninstalling QT and then reinstalling it,
    IE7 was unable to read PNGs (red X) and play quicktime videos in streaming.
    QT messed up registry in some way. It's been useless to redefine MIME-types
    and re-assign PNG file association. I re-formatted everything and started up
    again. :-(
    Hope you'll find a much easier solution...

    Sorry about that first post.

    I have seen this also be caused by the registration for the pngfilt.dll
    being corrupt.
    And a "regsvr32.exe pngfilt.dll" should correct this also. (that could be
    what the reg file on that web page is doing)

  7. And a "regsvr32.exe pngfilt.dll" should correct this also.

    There is no DllRegisterServer entry point found in pngfilt.dll and hence it can't be registered. BTW, this is case in my IE7 systems here. However, the module can be registered if you're using Internet Explorer 6.

    ---------------------------
    RegSvr32
    ---------------------------
    pngfilt.dll was loaded, but the DllRegisterServer entry point was not found.

    This file can not be registered.
    ---------------------------
    OK
    ---------------------------

    Hi,

    I know the link. I tried it but the merge failed with an error message
    saying it can't
    import because some keys are open by the system or other processes and not
    all
    data was successfully wriiten to the registry.
    I tried it in the safe mode, the same error message.

    Regards
    Gunter

    Gunter and Ramesh,

    I also tried the registry fix and received the error message that some files
    were in use. Also tried in safe mode and disabled almost every running
    process.

    I know it does not work for me (yet), but I'm glad someone identified the
    problem and is working on a fix. Thanks Ramesh.

  12. Same here. I get the same error message whether in safe mode or not. I am
    also glad that the issue has been identified. I am hopeful for a solution
    soon.

  13. It turns out to be a permissions problem. Start Regedit.exe and navigate to these keys one by one:

    HKEY_CLASSES_ROOT\MIME\Database\Content Type\image/x-png
    HKEY_CLASSES_ROOT\MIME\Database\Content Type\image/x-png\Bits
    HKEY_CLASSES_ROOT\MIME\Database\Content Type\image/png
    HKEY_CLASSES_ROOT\MIME\Database\Content Type\image/png\Bits

    See if you're able to read and write to the above keys. You can create a sample value to test.

  16. Hi John and Jim:

    I think we can work on this issue offline. If yes, drop me a mail (remove the string .XOX from my email id). In a recent case, the problem was identified as a registry permissions issue, and I'm yet to hear the feedback from the user on this matter.

    Ramesh,

    I just wanted to give you some more background on this issue. The .png
    issue started about 2 months ago. This computer is almost "bare" without a
    lot of software installed.

    I think I have narrowed the problem down to the UAC because .png images are
    visible if any of the following actions are taken.

    1. If UAC is disabled.
    2. If I log on as another user (guest).
    3. If I start IE as "run as administrator".

    Any of these 3 actions with bring back .png support.

    I have tried disabling "protected mode" in IE, Checking all IE settings and
    Add-ins.

    The only software that was installed prior to noticing the issue is
    Microsoft Office 2000 Professional, Macromed Flash Player, and Java
    (run-time). I'm not sure if the .png support stopped at that time. Also,
    there were several Windows Updates automatically installed prior to the issue.

    Thanks again,

    Jim

    I'm having the exact same problem. I succesfully used the registry fix(no
    error), but the problem remained...
