[Sorry, this should have gone into the Support section]
As a software developer, it was only last year that I learned out how to associate a file type with a program that I wrote and have the program open the data file and know what to do with it when I double-clicked on its icon. So I associated the TGD file extension with the Terragen 2 exectuable. But when I double click on my first project that I saved, Windows 7-64 gives me the following error.

However, I can load the file from TG2 and its seems to work just fine. File association with the editor I wrote for XP-32 works fine on W7-64 so I wonder what the problem is. It is a little tricky to get file association working because you do not have access to your debugger since the OS kicks your application off directly when you double-click one of its data file's associated icons. I just stumbled across how it works. The OS puts extra double quotes around the command line. These are not there when you call the program from a command line directly and pass it the data file's name. If you need a source code fragment to show how to handle it, just let me know.
