Error: Runtime Error when connecting to ArcGIS Server license in Windows Service
When creating an Engine application, the following error may be returned at runtime:
Failed to bind to an ArcGIS Server runtime. Ensure that the specified runtime is installed before running this application.
This error occurs when the code binds to the ArcGIS Server product, and the target platform in Visual Studio is set to 32-bit.
Solution or Workaround
When binding to the ArcGIS Server product, the target platform in Visual Studio must be set to 64-bit because ArcGIS Server is a 64-bit product.
