Installed Retail CD through PlayOnMac and Wine on Mac - OpenRCT2 needs file location?

[presfruit]

When I use OpenRCT2 and try to point it towards the RCT2 exe file (to my understanding, this is the game itself) it's just greyed out. Can anyone help me understand what I need to point OpenRCT2 to in order to run the game? I don't think I'm really understanding what files I'm supposed to select specifically for OpenRCT2 to run the game.
