I just downloaded the latest version of Aria into My Mac Pro Tower.  Following installing it to my computer, I check under "Get Info", to discover properties of the player and noted the box with a "check mark" saying, "open in 32-bit mode".  Of course, My Mac running with OSX 10.12 is 64-bit.  I took it upon myself to "uncheck" the box noting that there was no check box selection for "64-bit".  Does this mean that the Aria Player only operates in 32-bit only?  I would be grateful if someone would answer this question?  Thank you in advance and best regards.
