    Hi all,

    As you can guess from the title, IE7 no longer displays .png pictures, on
    any website.

    I have done all the usuall emptying of cache, temp files etc, and attempted
    the sfc /scannow just in case.

    If i right click the iexplore.exe in C:\Program Files\Internet Explorer and
    run it as admin, it does display the .png pictures...

    Frustrating is not the word.

    I can open and view .png in windows picture viewer etc, it is just IE7 that
    will not allow me too, FireFox works fine with them.

    I cannot repair IE7, i am not sure how to be honest. I have a new pc with
    Vista Premium pre-installed.

    Any input will be greatly appreciated!

    Thanks.

    Previous threads in this newsgroup about this behavior:
    http://groups.google.com/group/micr...ng+++graphics+++vista&start=0&scoring=d&hl=en

    If all Vista users saw this behavior, we'd expect something wrong with
    Vista. Since we only see three (3) threads (other than yours) about the
    issue in this newsgroup, the behavior's got nothing to do with Vista.
    What do you see instead of PNG graphics (e.g., a red x) on a website?

    Thanks Vincenzo for the link with the fix... However, I get an error message
    while trying to merge the registry files in Vista. Registry editor complains
    that some keys are used by the system or other processes.

    Btw, someone on that board suggested to reinstall a "codec pack" to solve
    this problem. I think all the problems with png images not showing in my
    Vista Explorer started right after I was browsing some web pages and seeing a
    pop-up window asking me couple of times to download a codec pack to watch the
    movie... I have always denied the access, but I think something might have
    changed/downloaded anyway.

  5. Reboot Vista in Safe mode and try again the .reg fix, Milan.

    Thanks for a reply,

    I made reboot in "save mode" and tried again the .reg fix but registry
    editor still says that some keys are used by the system or other processes.
    :(

    It might be a security program blocking the Registry changes it needs to
    make. A few, but not all, of the programs now doing this are:
    Ad-aware's Ad-Watch
    IBM Access Connections
    McAfee VirusScan and/or Antispyware
    Norton AV
    Spyware Blaster
    Spybot> Tools> IE Tweaks
    Spybot- Teatimer
    Spysweeper
    Spyware Doctor
    Windows Defender
    Zone Alarm (free) 6.5 Reported to be fixed in later versions.

    In the case of Zone Alarm 6.5 or Norton 2007 it actually has to be
    uninstalled. Make sure the Windows Firewall is turned on until you
    reinstall Zone Alarm.

    Hello Vincenzo,

    I have uninstalled Norton Internet Security 2007 from my pc but when I
    reboot in safe mode and try to use the .reg fix I'm still getting the same
    registry editor message... "some keys are used by the system or other
    processes".

    The PNG graphics problem pales in comparison to the possible hijackware
    infection you may have now!

    Run a /thorough/ check for hijackware, including posting your hijackthis log
    to an appropriate forum.

    When all else fails, HijackThis v1.99.1
    (http://aumha.org/downloads/hijackthis.zip) is the preferred tool to use.
    It will help you to both identify and remove any hijackware/spyware with
    assistance from an expert. **Post your log to

    http://aumha.net/viewforum.php?f=30, or other appropriate forums for expert
    analysis, not here.**

    If the procedures look too complex - and there is no shame in admitting this
    isn't your cup of tea - take the machine to a local, reputable and
    independent (i.e., not BigBoxStoreUSA) computer repair shop.

    Hi guys, thank you both for the help.

    I gave up on this issue... I have completely reinstall my vista operating
    system -- a little bit a pain, but no more problems with my explorer now.
