"Open With" from DropBox

Hey guys and gals,

I have Sonar 8.5, Sonar X1, and Sonar X2 installed on my Windows 7 PC.  I recently upgraded from X1 to X2 during the 1/2 price sale (thanks Cake/Roland).  I'm trying to learn my way around the new offering and like what I have seen so far.

A simple question (I hope).  I am trying to import a standard MIDI file from DropBox into X2 from an app on my iPad that supports standard MIDI files.  When I select "Open With" within DropBox, I have the option of opening in SONARPDR.EXE and that opens up Sonar 8.5 with the MIDI file displayed correctly.  However, I want to open it with X2 (or even X1) but when I select the folder where the .exe file of X1 or X2 resides, I still get the 8.5 .exe opening the file (my, a lot has change visually since then).

Any tips on getting MIDI files to "Open With" X2?

Thanks for any help that may be provided.
