MuseScore 3 crashes on start up

• Aug 9, 2020 - 21:34

I have seen a thread from 2019 that seems to cover this issue. I have tried everything which I will list below with no change on the start up crash.

  1. Fresh install of MuseScore 3 from a fresh download from the site. Still crashed on startup.
  2. Uninstalled and removed Musescore entries from the Registry.
  3. Fresh install of MuseScore 3 from same downloaded file. Still crashed on startup.
  4. Started MuseScore by clicking on an msz file. Musescore opened!
  5. Tested from icon again, but crashed.
  6. From Edit -> Preferences I unchecked "Show splash screen" and "Show start center and clicked "Apply".
  7. Tested from icon again, but crashed.
  8. Performed restore Factory settings: C:\Program Files\MuseScore 3\bin>MuseScore3.exe -F and followed the prompts.
  9. Musescore 3 opened, and I could open a score. Then I closed the score, and tried to open from icon again, but Musescore 3 crashed on start up again.

I now can only open from a previously saved score.

What else can I do?

I too am using an HP Pavilion Laptop, 64 bit, Windows 10 operating system and although I had intermittent crash problems with 3.5 alpha, beta and RC and initially had persistent crashes with 3.5.0, I have had no problems since running 3.5.0 with the "-F" command line option. However, my installation was not a fresh one. It started in the dim distant past with some version of MuseScore 1 and then has gone through various updates via 2 to 3 to 3.4.2. and then the various incarnations of 3.5 using downloaded msi files from MuseScore.org. I still have 2.3.2 installed. There is plenty there that could be making a difference between our installations, but let's start with a couple of more easily accessible areas:

a) What do you see when you look at the properties of the shortcut? In particular, what do you see in the Shortcut and Security tabs. Here is what I see:

b) what Preferences do you have set? I think the General Tab may be the most relevant and here is what I have. PrefGen.jpg

Thank you very much for these ideas. My icon properties are like yours. But having me check Security gave me an idea. I just opened the icon with "Run as Administrator", and it opened! I then matched my Preferences to yours, and tried to open as normal. It crashed. But now that I can open with "Run as Administrator", I'm going to see what is going on with Windows Security and my virus protection program. I think I'm on to something now
