I'm trying to open a file using an extension which can be dropped and used freely in new applications. But opening a particular MFA gives me this:
It's not in blocked extensions, and it loads fine in a blank program. I also removed a mfx file with a similar name just in case the two were conflicting. Even DllMain() isn't executed during the load; there's a first-chance CFileException (once), then subsequent attempts to load don't even throw that one.
I'm at a loss. Surely there'd be a different error message if it existed but couldn't be accessed. I attached the extension if you guys want to test.
