I'm trying to help someone configure Outlook 2003 as the default email client in their 64-bit Windows 7 Home Premium installation, but this program never appears in the list of "Default Programs" (pictured below) as an option (in fact, none of the Microsoft Office 2003 programs appear in this list).
I've also tried the "Detect & Repair" option under the Help menu, but this didn't make any difference either.
Is there a known compatibility problem with this scenario? Searching Google has turned up quite a few anecdotes with people experiencing the same problem -- the suggested solutions of "re-install MS-Office" (already done that) and "use a different email client" (the user specified Outlook as a requirement) don't resolve this in this case.
A Windows Registry hack would be greatly welcomed (I haven't found any for this with Google either).
Please note: A closed-source solution that somehow fixes Windows is not an acceptable solution because of the potential spyware factor, unless that solution is provided by Microsoft.
