I have an application built with Qt 5.5, deployed and running on x86 Windows 7 with dynamic linking. When I try to launch it on that particular computer, I get the following error:
This application failed to start because it could not find or load the
Qt platform plugin "windows".
Available platform plugins are: minimal, offscreen, windows, windows.
Reinstalling the application may fix the problem.
Try to use windeployqt. It'll try to autocollect all needed libraries.
