Most of the code is pretty generic, so I don't see much problems there. </SPAN><BR /><BR /><SPAN>However, I&nbsp; do have some problems creating the installer. To test this, I've written a small project containing only a simple basecommand and an installer class, and a setup project. If I compile on a </SPAN><STRONG style="font-style: italic;">9.2</STRONG><SPAN> machine, the installer works on both 9.2 and 9.3.1, but if I compile on a </SPAN><STRONG style="font-style: italic;">9.1</STRONG><SPAN> machine, it only installs on 9.1, and not on 9.2 or 9.3.1. The error I get is at the end of the install process, and says something like "Error 1001: Could not load all requested types. Retrieve the LoaderExceptions for more information". </SPAN><BR /><SPAN>I've googled this message, and it is related to one or more assemblies not being found (I suspect it's about ESRI.ArcGIS.Utility, or one of it's dependencies). So apparently there's a subtle difference between 9.1 on one hand, and 9.2/9.3.1 on the other.</SPAN><BR /><BR /><SPAN>Has anyone ever been in this situation, or seen this error message? Can anyone tell me how to retrieve the LoaderExceptions (the error occurs </SPAN><SPAN style="font-style:italic;">before </SPAN><SPAN>the installer class is instantiated, so I wouldn't know where to put a try...catch)</SPAN><BR /><BR /><SPAN>My environment is Windows XP, Visual Studio 2005 (or 2008, tried both) with VB.Net.</SPAN><BR /><BR /><SPAN>Regards, Berend</SPAN></BODY></HTML> Wed, 05 May 2010 16:14:11 GMT https://community.esri.com/t5/arcobjects-sdk-questions/installer-that-supports-both-arcmap-9-1-and-9-3-1/m-p/8986#M221 BerendVeldkamp 2010-05-05T16:14:11Z Re: Installer that supports both ArcMap 9.1 and 9.3.1 https://community.esri.com/t5/arcobjects-sdk-questions/installer-that-supports-both-arcmap-9-1-and-9-3-1/m-p/8987#M222 <HTML><HEAD></HEAD><BODY><SPAN>Hi, do you got the solution for this quesiont?&nbsp; My application is installed fine with ArcMap 9.3.1.&nbsp; But when I upgrade it to ArcGIS 10 and have ArcGIS Addin to create extension/toolbar, the installer has the same error message.</SPAN><BR /><BR /><SPAN>Thank you,</SPAN></BODY></HTML> Wed, 15 Sep 2010 14:54:38 GMT https://community.esri.com/t5/arcobjects-sdk-questions/installer-that-supports-both-arcmap-9-1-and-9-3-1/m-p/8987#M222 SJChen 2010-09-15T14:54:38Z Re: Installer that supports both ArcMap 9.1 and 9.3.1 https://community.esri.com/t5/arcobjects-sdk-questions/installer-that-supports-both-arcmap-9-1-and-9-3-1/m-p/8988#M223 <HTML><HEAD></HEAD><BODY><SPAN>Unfortunately not.</SPAN></BODY></HTML> Thu, 16 Sep 2010 11:11:14 GMT https://community.esri.com/t5/arcobjects-sdk-questions/installer-that-supports-both-arcmap-9-1-and-9-3-1/m-p/8988#M223 BerendVeldkamp 2010-09-16T11:11:14Z
