    Vista Ultimate x64, Outlook 2003 and IE7: Whenever I click on a link in my
    Outlook inbox, I receive an error message "this operation has been canceled
    due to restrictions on this computer". How can I change this? It's
    frustrating to have to copy and paste links into IE7. I running as the
    Admin.

    Thanks.

    Now, if you hadn't installed Firefox you wouldn't have that problem. :)

    Seriously, that's actually it. There is a conflict in which program should
    handle it. To fix it you need to make IE your default browser. To do so, open
    the Default Programs control panel, select "Set your default programs", and
    make sure IE has all its defaults.

    Thank you Jasper. You are correct...I did try, but without success, as it
    seems you already know. Your advise worked and the PROBLEM IS FIXED! I
    have searched and searched but no one has been able to help until you. You
    have been very helpful. Thanks again!

    No worries. :)

    I only happen to know because I ran into the same thing about three months
    ago.

    Do you have any other web browsers installed? Safari maybe? Could you dump
    out the contents of the htmlfile reg key (and subkeys) and put it in the post
    so we can see what it says?

    No other browsers installed.
    recovering to an old restore point didn't work (may not have had one old
    enough)

    Windows Registry Editor Version 5.00

    [HKEY_LOCAL_MACHINE\SOFTWARE\Classes\htmlfile\shell\open]
    @="Open in S&ame Window"
    "MUIVerb"="@ieframe.dll,-5732"

    [HKEY_LOCAL_MACHINE\SOFTWARE\Classes\htmlfile\shell\open\command]
    @="\"C:\\Program Files\\Internet Explorer\\iexplore.exe\" -nohome"

    [HKEY_LOCAL_MACHINE\SOFTWARE\Classes\htmlfile\shell\open\ddeexec]
    @="\"file://%1\",,-1,,,,,"
    "NoActivateHandler"=""

    [HKEY_LOCAL_MACHINE\SOFTWARE\Classes\htmlfile\shell\open\ddeexec\Application]
    @="IExplore"

    [HKEY_LOCAL_MACHINE\SOFTWARE\Classes\htmlfile\shell\open\ddeexec\Topic]
    @="WWW_OpenURL"

    That looks correct to me. Could you have a software restriction policy
    installed?

    Please humor me and go into the Default Programs Control Panel and set it to
    use Internet Explorer as your web browser.

    As far as I can tell IE7 is the default web browser. In "set your default
    programs" it is listed at the top and says "this program has all its
    defaults". There is nothing on that screen to indicate that it is not the
    default (so the "Set this program as default" button seems a bit silly AND
    gives no indication of a change when you press it anyway but that may all be
    because I don't have any other browser installed/available - but that is not
    my concern right now.)

    In "set program access and computer defaults" the "microsoft" details says
    web browser is "internet explorer" and email program is current program (with
    outlook and mail enabled). Same for non microsoft. Custom says use current
    web browser and email with access enabled.

    I have also "reset internet explorer settings" and disabled "third party
    browser extentions"

    OK this is interesting. Something I just discovered. I wanted to try to
    isolate the problem to OFFICE, as I have only seen the problem so far in
    outlook and word, so I was looking around for a non office program that might
    be able to launch a web browser but the first thing I bumped into was
    PowerPoint (another office program) ... and I CAN launch the web browser from
    PP (I entered a web address, pressed F5, then clicked the link and it
    worked).

    SO. IE7 is fine. Vista is fine. Powerpoint 2007 is fine. Outlook, Word and
    Excel however!!!

    I can also launch a web browser from Norton and Adobe Reader. Do you know of
    any other standard programs I can test that might help define the scope of
    the problem or is the above info enough?

    I am not aware of installing any software restriction policy. Is there a way
    I can check if there is one?

    I have the latest Norton Internet Security and Protection Centre and up to
    date definitions and Windows Defender is also up to date.

    UAC is off.

    Does any of that shed any light?

    I don't know what to say here. The error message you give indicates that you
    have an error with how IE is registered. Here is a KB article discussing it:
    http://support.microsoft.com/kb/310049/en-us.

    If you have another computer I would try what the article says about
    exporting the entire htmlfile key, with all sub-keys from a computer that
    works and import it into this one. Beyond that, I don't know what might work.
    This is not a security problem as far as I am aware, but rather a problem
    with how IE is set up.

    OK thanks for your help J
    I will try exporting the reg key from another vista machine when I can lay
    my hands on one but I don't hold much hope for that being the answer since it
    seems to work from all applications except outlook, word and excel.
    I'll also try asking on the office discussion group.
    regards
