Building a Managed Client to Run on a 64-bit Operating System

  • Article

To run a 32-bit client application on a 64-bit operating system, you must build the application by specifying "x64" for the /platform compiler option. If you specify "x86" or "anycpu", an E_DRM_MANIFEST_VIOLATION error code is returned. For more information about the /platform command line option, see the /platform (Specify Output Platform) (C# Compiler Options) topic on MSDN. For more information about identifying the output platform when using Visual Studio, see Build Page, Project Designer (C#).
