File Saving Issues

Hello, I'm a new user of MuseScore. I've recently downloaded and installed version 3.0.0.4785.

I am an advanced computer user... I've been in web design for 20 years and I program in php, Java, and JavaScript. I am only telling you this so that I establish my ability as an advanced computer user. This is so that the issue I'm reporting isn't just assumed as "user error".

I am on a Windows 10 Pro machine, 64 bit, OS build 17134.472

I started a new score in MuseScore and immediately attempted to save it via File > Save As.

The default location for saving… C:\Users\USER\Documents\MuseScore3\Scores\

When I clicked the Save button, I received the following error message…

“ C:\Users\USER\Documents\MuseScore3\Scores\FILENAME.mscz You don’t have permission to save in this location. Contact the administrator to obtain permission.
Would you like to save in the USER folder instead? “

I clicked the No button.

Then I attempted to save the file to the Documents folder. I received the same error message as stated above.

Then I attempted to save to a subfolder inside the Documents folder. I received the same error message as stated above.

I have never had any problems saving to the Documents folder or a subfolder in the Documents folder when using any other program. Just to be sure, I checked permissions on the Documents folder, and I checked permissions on the subfolder in the Documents folder that I attempted to save the score to, and also permissions on the default Scores folder (right click on folder > Properties > Security tab) There are three names in the "Group or user names" pane... SYSTEM, USERNAME, and Administrators. All three User Names have permissions for Full Control, Modify, Read & execute, List folder contents, Read, Write. And this was true for all three folders where I attempted to save the score.

I have checked User Accounts and see that I am part of the Administrators group.

I rebooted my computer and still have the same issue.

As an FYI, I have no issues with saving (as an example) a Word document or a psd (Photoshop file) to the Scores folder.

I am able to save the score to the Desktop as well as a subfolder on my Desktop. And I am able to save the score to my USER folder. I am able to make edits and save the file (File > Save or Ctrl + S) with no issues.

As an experiment, I copied (Ctrl +C) the file from my Desktop and pasted it into the Scores folder. From the MuseScore program, I opened the file that I had pasted into the Scores folder. I made some edits then attempted to save the file via File >Save, and I also tried Ctrl + S.

I received an error message that says “Open Temp File C:/Users/USER/Documents/MuseScore3/Scores/FILENAME.mscz.temp failed: No error"

To further experiment, I instead did File > Save As each time I needed to save the file. Each time I did this, it saved to the same location…. MuseScore3\Scores folder. This appeared to work just fine - no error messages... Just the typical message that said FILENAME.mscz already exists. Do you want to replace it? Each time I clicked the Yes button.

After doing a few more edits and saving (File > Save As) the file, I then closed the file, then closed the program. I re-opened the MuseScore program, then re-opened the file from the Scores folder and the only data that was there was the title, the composer name, and a blank grand staff - so basically none of the edits I made after I pasted the file from the Desktop to the Scores folder were saved even though (via File > Save As) it appears to save with no issues.

This was not just a one off as I tested the issues described with a whole new MuseScore file.
1) Cannot save to the default Scores folder.
2) Cannot save to the Documents folder
3) Cannot save to a subfolder in the Documents folder.
4) Any attempt to saving to any of the folders listed above results in a “You don’t have permission to save in this location. Contact the administrator to obtain permission” message

1) Saving to the Desktop, or a subfolder on the Desktop, or my USER folder works fine. Edits can be made and properly saved.
2) If the file is copied from the Desktop or a subfolder on the Desktop and pasted into the Scores folder, then opened from the Scores folder into MuseScore program, the file cannot be saved via File > Save or Ctrl + S. An error message pops up that says ““Open Temp File C:/Users/MYUSERNAME/Document/MuseScore3/Scores/FILENAME.mscz.temp failed: No error"”
3) Saving via File > Save As to the Scores folder appears to work, but no edits get saved. If you close the file and re-open it, nothing you’ve added in is there.

I’ve done a Google search on the issues described and it appears that there’s quite a bit of “Seems like user error” or “Seems like a permissions issue” type replies in response to people who are having the same issues. As a programmer, I am pretty meticulous when it comes to testing and I am certain this is not user error. And, as previously described, I have full permissions on the folders in question. I’ve never had any issues saving to any of my folders with any other program.

I can work around it by just saving all my scores to a subfolder on the Desktop, but I thought it best to report that there are issues saving to other locations including the default Scores location.
