Cannot save at all either to the cloud or to my computer

• May 5, 2025 - 12:00

I cannot save any scores whatsoever. It happens when I open a new score and immediately save it and it happens to older scores as well. I've tried saving to a different folder with no luck. I've completely uninstalled and reinstalled Musescore as well, also no luck.

The error is 'Your score could not be saved; an unknown error occured while saving this file'. It happens to every score I try and save, even brand new ones. Can anyone help?

Thanks. However I have no other place to store them. My documents is automatically part of OneDrive, as is my Desktop and everything else. I've got no other drives to save my scores in.

I've been using Musescore for ages, always saving into the same Musescore4 folder (where it automatically installs to) and never had a problem until now.

The logging around save errors is far from optimal. Basically whenever an error happens, the error state is recorded but not the error itself so in the end MuseScore shows this very generic and unhelpful "Unknown error occurred" message. I have created an issue to improve this: https://github.com/musescore/MuseScore/issues/26165. I have the code changes done but I was waiting for 4.5 to be released. I should go back to it and submit a PR.

It all looks like permissions issue indeed - we saw issues with OneDrive previously. Or an antivirus.

misspwright, I hope you will read this:
1. Do you have the following two files on your computer?
C:\Users\phoeb\AppData\Local\MuseScore\MuseScore4\shortcuts.xml
C:\Users\phoeb\AppData\Local\MuseScore\MuseScore4\midi_mappings.xml

Can you open them in any text editor, e.g. Notepad?

  1. The logs show that MuseScore managed to save to the following three folders:
    C:/Users/phoeb/AppData/Local/MuseScore/MuseScore4
    C:/Users/phoeb/OneDrive/Email attachments
    C:/Users/phoeb/OneDrive/Documents/Scores

Can you try to save in them?
