Can x86 store apps be run on x64 devices?

    Question

  • For my native C++ Windows Store app to be supported on "all" Windows 8 devices, are the x86 and ARM platforms enough, or must I also distribute an x64 app (and therefore ensure that my native C++ code works on 64-bit platforms)?

  • Yes. x86 apps can run on x64 systems. If you have an x64 system you can test this yourself by building and deploying an x86 app (by default, Visual Studio will build x86).
