msimn.exe deleted - need to reinstall Outlook Express
 

I'm helping a friend whose PC is running Win XP Home. She did not do a
proper powerdown/powerup,
got a blue screen on reboot, ran dskchk (with option to fix errors) and
could not run OE 6 because msimn.exe is missing.

Her dbx files seem to be OK. We need to reinstall Outlook Express. I've
looked around with Google for suggestions for this
and finding a variety of suggestions - some talk about reinstalling SP2,
other IE6. Some involve registry changes. Isn't there some way to do this in
a straightforward, simple way?

Any suggestions would be appreciated.

Would installing Windows Live Mail go out and find and install the dbx files
when it is installed?

Many thanks -- Sam
