The Insider Preview versions can and do have problems.  I don't have my iLok on my Insider installation.  Just my "production" Win 10 OS.  I have Sonar (but not most of the MIDI or plug ins that require activation) installed on the Preview version but mainly as a "backup" in case I had a recording session and ran into a problem that couldn't be resolved.  I can continue recording with the Preview version and then later after the Production system problem is resolved do what I need to do with it.
