Linda,

Are you adding assemblies to the Application Folder or to the Global Assembly Cache Folder? If you want them installed in the GAC on the target machine you should be following these instructions from the Dev Guide:

Installing MM .NET assemblies into the GAC on a Production Machine

1. Add a deployment project to your solution
   
   
2. Right-click the deployment project, and select View | File System from the shortcut menu.
   
   
3. In the File System pane, right-click the File System on Target Machine node and select Add Special Folder | Global Assembly Cache Folder.
   
   
4. Right-click the new Global Assembly Cache Folder and select the Add Assembly from the shortcut menu.
   
   
5. Add the following assemblies from the Select Component dialog (if you are using any MM .NET third party controls, also select these assemblies):
   
   
   • Mere Mortals Framework 2005
     
     
   • Mere Mortals Framework Interfaces 2005
     
     
   • Mere Mortals Framework Windows Forms 2005
   
   
   
6. Click OK to add these assemblies to the deployment project's GAC folder.

Best Regards,
