Hi everyone
I have a code written for BO 3.1. I am changing the schema names for this application with universe (unv). BO system was upgraded to 4.1. I need to upgrade my code. I need to add my designer.dll as a reference in my project. But I get the following error
"A reference to ‘Business Objects DEsinger 14.0 Object Library’ could not be added. Could not regsiter the Actives type library. '\desinger.exe "
How can I resolve this error

Unlike with the 3.1 installs, designer.exe does not automatically register with COM when it’s installed. So, you need to register it to get this working. To do this, run a command prompt (as administrator if you have that option…), navigate to the win32_x86 subfolder of your BusinessObjects install and then run:
designer.exe \RegServer
Note that this is case sensitive!!!
When the Universe Designer appears, close it. You should now be able to find two versions of “BusinessObjects Designer 14.0 Object Library” in the COM Type Libraries list in the References section of your project. Select the one with version 20.0.
