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

[Alexander Dyagilev]

I've removed all the code from my project.

Left this:

#include<QGuiApplication>

intmain(intargc,char*argv[])

{

QCoreApplication::setAttribute(Qt::AA_EnableHighDpiScaling);

QGuiApplicationapp(argc,argv);

return0;
}

Still getting the same error! Of course, all those 3 DLLs are not used anymore so the problem is not in them.


Strange problem...
