Yes but you may be in for a bumpy ride. Finale 27 is 64 bit only while 2014 was 32 bit. The Aria player will be upgraded—it’s the second installer in the download so make certain you run that, too. Paths may have to be tweaked and so on. Keep track of your Garritan authorization files and so on.

Many users uninstall everything and start from scratch but I would see if the upgrade process works as it should first. Others may disagree. MM is still supporting Finale through August 2025 so, if you are going to do this, now’s the time.

thanks so much!
