For some reason my computer refuses to open MHT files.

I first noticed it when I started programs that use them, eg BitComet.
I would always get a File Download dialog:
http://i44.photobucket.com/albums/f9...leDownload.jpg
Clicking on Open, Save, or Cancel produces the same result - nothing
happens.

The application that requires the file comes up with an Action
Cancelled error before the File Download dialog appears and stays like
that, regardless of which button I press:
http://i44.photobucket.com/albums/f9...nCancelled.jpg

If you try to open the file through IE (File > Open), I get the same
File Download dialog, but IE remains unchanged - no error at all. The
file just won't open.

I tried going into the File Types section of Folder Options and making
sure that the MHT and MHTM sections had speech marks in the right
places (ie around the %1 and so on) as per this old thread from 2002:
http://tinyurl.com/ec5pw. However, it made no difference.

I was just about living with it, but it's now annoying me loads! Hope
someone can help.

Cheers

Hi MKS,

Download FileExtInfo.zip from this URL:
http://windowsxp.mvps.org/fileextinfo.htm

Unzip and run the utility. Select .MHT from the listing, and generate a
report. Post the full information here.

Hi MKS,

The file association looks all right. Open the following folder and note
down the file names listed there:

%Programfiles%\Internet Explorer\Plugins

Post the details here.

I have no Plugins installed and the mht file. See if *temporarily* moving
the files to a different folder helps. If that helps, then you need to
isolate the problem by moving them back one at a time.

Also, if you have the following registry key, backup the branch to a REG
file and delete the key.

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet
Explorer\Plugins\Extension\mht

To open Registry Editor, type Regedit.exe in Start/Run.

Moving all the plugins makes no difference, and that registry entry
doesn't exist. :-(

The only difference I found in the registry export is for the "EditFlags"
value.

In my system (fresh installation), the EditFlags value is dword:00000000

See if fixing that helps.

Also, check this registry key:

HKEY_LOCAL_MACHINE\Software\Microsoft\Internet
Explorer\Plugins\MIME\message/rfc822

The above branch does not exist by default. If it's present, backup the
branch to a REG file and then delete.

I changed the EditFlags entry and that MIME registry entry doesn't
exist.
I still have the same problem. :-((

I'm running out of ideas MKS
