Add EditPlus program to list of Default Programs?

I've spent several days trying to get several files extensions to be the default file association for EditPlus (EP). I've used a standalone program that manually sets the registry to point to the full path of the program, "C:\Program Files\EditPlus 3", and tried setting it myself to the correct path. The results are that I can then double click on a txt file and have EP load, BUT that very process causes the associations to be reset to "EDITPLUS.EXE" with no path and an incorrect file name -- it should be "EditPlus 3".

The mystery is not so much as to how to register EP to be associated with .txt (and others), but why, when I do get it set, it bounces back the first time I use it, as if I hadn't changed it at all.

Thanks for the tip. Following your instructions to a "T" it works and EP is indeed loaded, BUT it reverts back to Notepad the next time I double click a .txt file. There's something going on that's resetting the default I'd love to put my finger on.

Thanks, yes I did specifically check the "always" box. The default program that comes up after initially working is Notepad.

The program is Microsoft's Windows 7 Ultimate Notepad.exe.

Wow, this one was an important partial success! I entered txt, inf, ini, log, nfo, sav into the box. As a result double clicking on a .txt or an .sav brings up EP predictably. The others open up on WE with an EP icon but continue bringing up Notepad.

Here's the exported reg file you asked for. It was created before I saw this post.
