I alaways installed the arcObjects with the same version as Engine, or Desktop.</SPAN><BR /><SPAN>I never tried otherwise.</SPAN><BR /><SPAN>But anyway, to think as a programmer.</SPAN><BR /><SPAN>The SDK .NET is just installing the wrapper or library interfaces to .NET on top of the already installed COM library.</SPAN><BR /><SPAN>So, the engine will install the real COM libraries, and SDK will install the wrapper to call them from .NET.</SPAN><BR /><BR /><SPAN>Now COM don't have versions (that I know of). so it might be that the .NET wrapper will be able to call the COM libraries of the engine.</SPAN><BR /><BR /><SPAN>So, logically as long as the wrapper are later than the engine (assuming it is backward compatible), then should not be a problem.</SPAN><BR /><BR /><SPAN>But you have the opposite. so it might work for most of the cases, but fail on some new features in Engine.</SPAN><BR /><BR /><SPAN>As I said, what I said, just "logical thinking", and practically I don't have any experience doing something like that.</SPAN></BODY></HTML> Thu, 04 Apr 2013 18:17:11 GMT https://community.esri.com/t5/arcobjects-sdk-questions/arcgis-engine/m-p/151568#M3923 GhassanKarwchan 2013-04-04T18:17:11Z
