Does it work for example applications? Trying that would at show whether it’s the tools or something in your project.


Yes. Gallery example runs fine.

Did you also rebuild all your DLLs for UWP and are all your DLLs UWP compatible?


Yes, of course. All these my DLLs are Qt-based DLLs and thus should be UWP compatible. Am I right?



The error itself reads a bit like https://bugreports.qt.io/browse/QTBUG-54251 but then again, I fixed that for 5.7.1. However, there might be some information valuable for you as well.

*Subject:* [Interest] Can't run Qt application under UWP kit

Hello,

My app is Qt Quick Controls 2 based app. Qt 5.7.1, Windows 10, Visual Studio 2015.

Desktop 32bit version works fine.

But when I switch to *Qt 5.7.1 for Universal Windows Platform 32bit* kit, it fails to run with the following error:

winrtrunner --device 0--start --stop --install --wait 0--profile appx C:/Work/Source/build-MusicPlayer-Qt_5_7_1_for_Universal_Windows_Platform_32bit-Release/bin/player.exe
qt.winrtrunner:Usingthe Appxprofile.
qt.winrtrunner:Failedto activate application:0x8027025b"The app didn't start."
Errorwhileexecuting the WinRTRunnerTool:Processcrashed

It states here <https://forum.qt.io/topic/50638/start-application-on-winrt> that some dependency is missing. I've checked it using Dependency Walker and it seems that all the required DLLs are in the application's folder. I've also tried to copy just all the files from Qt kit installation into app's dir.

My application consists of one main executable and three .DLL files. I've launched windeployqt for the each of them. Tried both debug and release versions.
