The latest non-store version isn't necessarily more stable, but it has been updated with bug fixes and some functional improvements. Both the installer and the portable receive updates (patches) much more frequently than the store version. I suggest using the portable version, making sure you place it in a NON-Windows controlled directory. Something like C:\MusicBee. The added bonus of using the portable is that you can copy it to a flash drive and move it to another PC very easily. Or copy the entire directory as a backup.
