WinRT: [x64 MSVC2015] Examples not starting

If I try to run qmake on any of the Qt examples, I get the following warning:

WARNING: winrt_manifest_install.path is not defined: install target not created

The package manages to compile, but as soon as it starts, it will show up for a very short moment before crashing with the error:

qt.winrtrunner: Failed to activate application: 0x8027025b "Die App wurde nicht gestartet."

Please note: I tried about 10 different examples, both for widgets and qtquick, and I made shure all dependencies are there. If I use the msvc2015 compiler for normal win32 applications, it works.
