Thanks, David. You and I seem in much the same boat here, so I hope someone else weighs in.

The only documentation I have found on this is basically the HKCR mechanism as I described it. I have never found documentation on the parallel universe of "Open with" and the HKCU entries you mention.

The existing pre-Vista version of my apps used the MFC CWinApp::RegisterShellFileTypes(). My instructions to the user for changing the association were to delete the .ret file association using Windows Explorer, and then run the program that he/she wants to get the association (RegisterShellFileTypes() will not steal an association, just grab an extension that is not already assigned).

One of the first things I discovered with Vista was that this RegisterShellFileTypes() method does not work on Vista, even after a clean install (it is not even virtualized if you do not have a Vista-aware manifest). So I moved the file association code to my setup program, which runs as admin.

That is where I am right now, wondering how to change the association in my non-admin application.
