Windows RT Demo not Working

edit

Hi, I tried to run Windows RT Demo with the OCV 2.4.6 on Win8.1. The project is builded and the preview works. But when i click the apply button it crash with the following call stack:

msvcr110d.dll!Concurrency::details::_ReportUnobservedException() Line 2455 C++

Any ideas ? Thanks
