The ArcObjects Primary Interop Assemblies (PIAs) now target the X86 platform. Since ArcObjects PIAs are 32-bit applications, this modification allows you to safely run your ArcObjects applications on a 64-bit machine. The X86 target platform specifies to the common language runtime (CLR) that the assemblies must run as 32-bit processes, even on a 64-bit machine. For more information on the impact of this modification and how to modify your project settings to target the X86 platform, see Migrating ArcGIS 9.3 Desktop and Engine custom components to ArcGIS 10.
Build it as x32 applicationi.e. targeting the x32 platform. It builds and runs fine, except it fails to retrieve the available licenses.
ArcGIS Pro (not yet released) will support x64 but will be a different API.. Could you please give me more details about this API?
Sorry to ask the obvious but exactly what licenses do you have? My guess is that there is a problem with your license(s).
The ArcGIS Pro API has not yet been made available so it isn't possible to provide future information on it.
