Windows 7 - Default Programs & Setting Associations

I have installed Xemacs for windows and I'm having a problem associating it as the default program for .txt files. I know the standard process, but that standard process doesn't work. I have "Windows 7 Home Premium installed on a 32 bit system. I go thru the standard process via Default Progams/Associate a file type/ process and then browse to the Xemacs application. When I select it, nothing happens. When I check the association, it's shown as "Unknown application". Note: I have a 64bit system that handles the assocation just fine.

Also, on the original system, the choices for default programs is very limited. It seems that programs I have installed some how are not being populated in the eligible "default programs" list?

Any ideas? Is there a brute force way to add programs to the Windows 7 default programs list?

Can you browse to a .txt file, right click, choose "open with" and then navigate to Xemacs and open the file?

No! Likewise going thru "control panel/default programs" doesn't work either.

Turns out there is a free default program editor that allowed me to solve the issue.

The default program editor is available at Download | Default Programs Editor.
