I just updated Qt using Maintenance Tool. Now when I run application in release mode I get 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.

Reinstalling the application may fix this problem.

This solution did not help me: https://stackoverflow.com/a/20496175/1034253

In debug mode the application works good.

  • Are you trying to run it from the Qt creator? You might need to remove the build directory entirely because Qt 5.4.0 was not binary compatible on Windows. – Simon Warta Feb 26 '15 at 23:24

check the other Qt dlls in your executable directory. For release mode you must always use the release version of the dlls. For Example Qt5Core.dll instead of Qt5Cored.dll
