If you double click a file in the Finder and you get a dialog box that
says:

     The application "Teach" can't be found for this document.

with "Cancel", "Try Again" and "Locate..." buttons, using the locate
button to find the application and clicking the "Open" button will
allow documents of that kind to automatically be loaded by that
application.

However, in this case, the document's file type has already been
associated with that application.  The application just wasn't in the
place that Finder thought it was.

If you double click a file in the Finder and you get a dialog box that
says:

     An application can't be found for this document.

with only a "Cancel" button, then no file type association has been
made.  You can associate an application with that document type
temporarily (for a single launch) by holding down the Option key while
double clicking a document and you will be asked to find the
application to open the document with.  This is handy if you normally
have a file type associated with an application you normally use to
deal with that type of document but want to load the document in
another application without actually changing the association.

To permanently change the application associated with a particular
file type, hold down both Option and Control while double clicking a
document.

You can, of course, do these type of file type associations using
either the old style icon files or the newer style rBundles.
