There is no msimx.exe that I ever heard of.
If you are using Outlook Express then msimn.exe is licated in C:\Program
Files\Outlook Express
I have no idea what .omf files are or what they should be associated with.

I need the missing msimx.exe file? So it will open the attachment with
Outlook Express...

If you do:

Save the attachment to your HDD. Right click on it and Open With | Choose
Program. Find and choose a program that works and then check the box:
Always
use this program to open this kind of file. This should enable you to
open
these attachments in the future.

If you don't have a program listed, here is the site for IrfanView.

Download IrfanView at:

I have received emails with .emf attachments. I understand that I need
to
associate this file extension with msimx.exe, but this file is missing
from
my Outlook Express folder. How do I install this missing .exe file?
