After installation, 3.1 won't launch
Just downloaded and installed the May28 release; it removed the round taskbar icon for MS3, but put a new rectangular icon on the desktop. When I click that, I get a dialog box with:
X The item referred to by this shortcut cannot be accessed. You may not have the appropriate permissions."
The same thing happens if I try to launch it from the list of apps on the left side.
The shortcut is to "C:\Program Files\MuseScore 3\bin\MuseScore3.exe"
Running Windows 10, 64 bit as Administrator. Before the upgrade, MS worked OK.
MS 2.1 appears to run normally, but it cannot open the files I want to use because they were saved using a newer version.
Ideas? Next steps?
