Unable to Install new MuseScore 4.3

• May 8, 2024 - 18:27

I'm trying to install the new MuseScore 4.3.0 (Specifically MuseScore-Studio-

I downloaded the .msi installer, but every time I try to run it, I run into issues during the "removing software" step. It consistently pops up an error box that reads:

"The feature you are trying to use is on a network resource that is unavailable. Click OK to try again, or enter an alternate path to a folder containing the installation package 'MuseScore-' in the box below." (the source mapping/file path box is under the message)

I have searched my entire machine for that 4.2.1 .msi file or any other file containing part of its name, and there just isn't one... Not on my local machine or any of its users.

When I cancel the search since the file cannot be found, it says "The old version of MuseScore4 could not be removed. Please contact your support team."

I decided not to uninstall my old version myself, because I found a similar forum post from someone dealing with a 3.6 installation for whom that didn't work.

Is there a solution to this? Or maybe some way to download the 4.2.1 .msi file that the program is looking for so I can try to point the installer at it?

NOTE: I've never had a reason to touch registry keys or files/locations for MuseScore, so I have no idea why the file wouldn't still be on my machine if it was actually installed with my last version.

(PLEASE don't tell me to run the installer as an administrator. msi files don't do that. They request admin permissions as they encounter them, which this installer is doing. I have already tried forcing it to run as admin anyway and it makes no difference.)


Update... I fixed it. Here's the blow-by-blow:

I found and downloaded the 4.2.1 msi file from the GitHub link here: https://github.com/musescore/MuseScore/releases
Then tried to run the installer pointed at that file where it had saved in my downloads. It closed abruptly after (presumably) running.

I opened MuseScore again and was again prompted to install the latest version, which I did. Part way through the installation (second time) I was prompted to either remove previously installed MuseScore files or repair them. I selected the repair option and the process (supposedly) completed and MuseScore closed again.

Upon opening MuseScore for a 3rd time since installing the .msi file from GitHub, I was prompted to install the update AGAIN and confronted with the same setup window giving options to either Repair or Remove and this time selected Remove. Then, I finished the setup wizard as usual.

After opening MuseScore for a 4th time to see if it had worked, I was ONCE AGAIN prompted to install the update. I followed the setup wizard again through all the indicated steps, and finally, after closing the program through the setup wizard with the "launch MuseScore 4" radio button selected, it booted up with no update prompt on the 5th try (since downloading the GitHub file).

Oof. This installer is horribly inefficient and someone in the developmental continuity department needs either a raise or a forced vacation for this previous version installer file bull hockey.

TLDR of my solution:
If you happen to run into any part of the same thing as I did, save yourself my headache and do this:

  1. Grab the installer file (for whichever previous version your setup wizard directs you to find) off of GitHub at the link above or by following the previous versions tree here: https://musescore.org/en/download (Scroll down to Older and Unsupported Versions to find what you need.)

  2. After downloading, run the setup wizard (open MuseScore and update when prompted) and direct it to the newly downloaded older version installer file (the .msi one).

  3. Run the setup wizard a second time and select "Remove" when asked what to do with old MuseScore files.

  4. Run the setup wizard a third time and complete the process fully to install your new and completely updated version of MuseScore.

Jesus Christ, this was such a headache. There goes 2 hours of my workday trying to do this stupid update. What a bad taste in the mouth... ugh.
