With the release of 10.0 ESRI offered the AddIN, this is great and makes life a lot easier. But I have concerns about compatibility. Can an AddIN built in 10.1 be installed and run in 10.0 assuming it does not use functionality specific to 10.1?&nbsp; I came across this thread </SPAN><A class="jive-link-external-small" href="http://forums.arcgis.com/threads/64733-backward-compatibility-of-a-10.1-Add-IN?highlight=addin+10.1+compatibility" rel="nofollow" target="_blank">here</A><SPAN> but no-one seems to have had any success.</SPAN><BR /><BR /><SPAN>So whats the official line on this? 10.1 AddIns are not compatible with 10.0? I hope not!</SPAN></BODY></HTML> Wed, 05 Sep 2012 18:19:08 GMT https://community.esri.com/t5/arcobjects-sdk-questions/backward-compatibility-of-10-1-addins-with-10-0/m-p/415993#M11187 DuncanHornby 2012-09-05T18:19:08Z Re: Backward compatibility of 10.1 AddIns with 10.0 https://community.esri.com/t5/arcobjects-sdk-questions/backward-compatibility-of-10-1-addins-with-10-0/m-p/415994#M11188 <HTML><HEAD></HEAD><BODY><SPAN>Add-ins are not backward compatible.
