An .exe file, huh?
That’s right. So people don’t worry.
This said, I would be remiss in not providing some information likely to be of help. First, the composer is none other than Tom Salta (http://www.tomsalta.com/) (Red Steel, GRAW series, and so on).
Next, two tracks can be definitively identified via comparisons to the samples available here (http://www.tomsalta.com/behindHAWX.html):
the very first track – the ‘menu theme’ – is ‘Ready Aurora’; and the briefing BGM (track 23, apparently) is ‘Artemis Ascendance’
Track 20 seems to be the Glass Hammer BGM; and track 12 is the results BGM.
