Musescore 3 won't open

• Dec 28, 2018 - 04:31

I just downloaded Musescore 3.0 in order to open an arrangement my friend sent me that he made on Musescore 3.0. I went through the installation wizard but when I try to open the app it, the blue opening window pops up for a few seconds then goes away, but the app never opens or even pops up on the task bar. I've tried running as administrator and restarting my PC and it still doesn't open. I'm on Windows 10 and Musescore 2.0.3 worked for 2 years up until today so I'm not sure what the problem is.

I have the exact same issue! I installed Musescore 3 on Dec. 26 (I was soooo excited to have it before I go to visit friends for the New Year) and it did EXACTLY what you said it does for you. Installation Wizard works fine but it won't open from any angle I try (desktop shortcut, file explorer, desktop shortcut Run as Administrator, file explorer Run as Administrator, etc). I tried uninstalling and reinstalling, restarting my laptop, everything I could think of. After a couple hours, I uninstalled it and put in a Contact Us form. They suggested I post in the forum so that everyone in the community could help and then I saw your post.
Did your laptop/Windows 10 update recently? Mine did two days before I tried to install Musescore 3 and I can't help but wonder if the update invalidated some of the program code.
Sorry I don't have a solution, but I hope one can be found for both of us.
Happy New Year!

My computer updated like last week I think but I'm not sure that's the problem. I managed to get MuseScore open by typing musescore.exe -s into "run" on windows but unfortunaetely that makes it so I think there's no acoustic review function which kind of defeats the purpose for me.

I have the same problem, on both stable Windows 10 and the latest Insider build. The program launches if the synthesizer is disabled, but it also crashes if an option is saved.

Had the same issue, started with "-s" disabling sound. Someone else had this issue and uninstalled Jack Audio to get it to launch, this seems to have worked for me as well.

I found a solution how to run Musescore 3. I have this problem too, but if you want to open Musescore 3 and work with this software, you should open one .mscz file (if you have in your PC one, or download it) and Musescore 3 will work !
I can't open it normally, but if I open one .mscz file, all works.
I hope this information was useful for you.
