COM SDK problem with reference designer.tlb


When trying to use COM SDK and add reference designer.tlb to my project in Visual Studio I receives the following message:

A reference to designer.tlb could not be added. Please make sure that the file is accessible, and that it is a valid assembly or COM component.

I'm using BusinessObjects XI 3.1

I want to create a tool to change passwords for existing connections.

I read that the only way to change the password of an existing connection is to use COM SDK.

Java SDK has no method to obtain a user name, connection parameters, etc.

I want to create a project in visual studio add com component (designer.tbl) and create application in C#.

I found a business object tutorial ( that shows how to do it. But it is rather old.

How to deal with the problem?

I wrote a post here COM SDK problem with reference designer.tlb but got a message to move it to this category.
