Failure to start MuseScore after build

• Sep 12, 2019 - 10:14

I updated my build environment to use Qt 5.12.4. on Windows 10.
Build proceeds fine both from conmmand line and MSVC, but MuseScore cannot be started.

The error message is :
This application failed to start because no Qt platform plugin could be initialized.
Reinstalling the application may fix this problem.

Seems something is missing from the setup, but I cant figure out what it is.


Moving the MuseScore3.exe to the installtion folder in C:\Program Files\MuseScore3\bin makes it run OK.

Could it be a PATH setting that is missing?
