    IE8 does not reckonize the newer powerpoint 2007 .pptx format and opens it as
    a winzip. Please update.

    Do you have PowerPoint or the PowerPoint viewer installed? What happens if
    you save to your HDD and open them from there?

    If there was a 'Urgent Request' button I would have used that... The choice
    is a question or suggestion. Hence... the suggestion to update IE8 to
    properly fucntion.

  5. Please state your full Windows version (e.g., WinXP SP3; Vista x64 SP2) when
    posting to this newsgroup.

    Is the PPTX file an attachment? Is it located on a network somewhere?

    It's not up to the browser to render every possible file format. You need an
    external plugin to read the format and deal with it. Either buy and install
    Office 2007, get the Office 2007 compatibility for Office 2000/2002/2003, or
    get the free Powerpoint 2007 viewer
    (http://www.microsoft.com/downloads/...40-14E1-467D-8DCA-19D2A8FD7485&displaylang=en)

    The reason it's being handled as a Winzip file is because that's what an
    Office 2007 pretty much is - it's XML that is then compressed using the Zip
    format, it most likely that the website you're downloading from is using a
    content type header that triggers IE to use Winzip to open it when Office
    2007 (or a plugin that can handle the format) is not installed on your PC.

  7. The problem is the Content-type and "MIME-sniffing"
    versus the suggested file extension. It's a security issue.
    The user has the option of overriding the security issue
    in the Security Settings (Miscellaneous section).

    A workaround is to rename the cached file's .zip extension
    to whatever may be more useful. I suspect dragging the
    cached file to an already open app which could receive it
    might work too but haven't tried it yet.

    In your reply you stated:

    The user has the option of overriding the security issue
    in the Security Settings (Miscellaneous section).

    Can you tell me where I could find that setting? Our server application w/ IE 8 attempts to always open on winzip for all clients. I have tried to change content-type / mapping but cannot seem to fix the issue. Any help is greatly appreciated.

    Thank you,

    Kris

    I have got the same problem.

    it's a vista 32 bit with office 2007. and i want to edit the file and upload it later. the workaround with saving the file is pretty lame for work. the files are located on an iis and provided in a wiki.

    i've also found a threat where sbdy suggested to turn of the phishing filter. but this is way too risky.

    thx

    So far my solution has been to switch to FF as they do not mess with the
    suffix of a file.
