I'm running Windows 8.1 (RTM) with Unity Pro 4.2, and I can't get any of my exported Windows 8 projects to run. When I do the build in Unity, it creates the Visual Studio solution. If I open that solution and try to run it (after switching to x86 target), I get these errors: This is just an empty project with no plugins and just a cube in the middle of the screen. I can't get the exported Unity project to run in Windows 8.0 or 8.1. On a side note, this project runs great on Android, Windows Desktop and Windows Phone 8. Has anyone else run into this issue?
