Setup project for .Net add-in

I've create an add-in and now I need to deploy it to clients.from what I understand the best way to do this is to create windowssetup project. So I did this and added the files to the dependancylist. I get an warning message:
Warning 39 Unable to create registration information for file named'Tank Volume Analysis.tlb'

I used the Solidworks supplied templates to create the add-in so ithas the register / unregister com methods in it. So far I've beenable to get the installer to install the files to the correctlocation but I still get a missing component error from swx when Itry to load the add-in. I assume that I need to register somethingand maybe it's the .tlb file that is causing the problem. Anyonehave an example they could share?SolidworksApi macros
