Hi Ben,

Thanks for reporting this. The installation behavior you are seeing here for the plug-ins is not correct. These should only be installed in the Plug-ins folder, so I will take closer look into this to see what could be happening with the updater.

Bingo. Same here.

Did you download and install 27.1 or did you update from within 27? I've done both over the last few days.

I did both. Looking at the contents of the installer package with Pacifist (an installer package browser), it seems clear that this duplication is exactly what the installers are designed to do. ....

I did both

As did I so… I did some uninstalling, downloading and reinstalling. The stand alone installers (27.0, 27.1 Beta, 27.1 final)  do not do this. Updating from within 27.0 does.

Still trying to figure out if other anomalies are related to 27.1 or a coincidence.

Is there any news on this? It should be easy to determine exactly what the install is doing.

What I found and Support confirmed is that keeping or deleting that extra Lyrics folder has no effect on 27.1. It only appears if updated from within Finale, not if 27.1 is downloaded separately from your MM account.

From what I can see, the full installer of 27.1 also installs these duplicate files. 

Yes, they won't be used or cause problems with the running of the program -- but they are nothing but 'cruft'; dead space on the disk which causes confusion for the user and speaks to MM's quality assurance.

I don’t know what you “can see” because it doesn’t. I have installed and deleted too many times to count by now and even did a clean install of Monterey, 26, 27, 27.1 and Note Performer on a new SSD to verify this and have kept Support informed along the way, The extra files show up for me only if 27.0 is installed and the update is done from within.

Without the ability to restore my system to a previous state in seconds through APFS Snapshots, none of this would have been possible. I’m also working with Apple Engineering on my other issues with crashing.
