How to deploy Office Shared Add-in

Suppose you have implemented shared add-in using VS 2008 for Office 2007 and now you have to create installation package.

unable to create specified activex control Office add-in error

Add-ins that directly implement ICustomTaskPaneConsumer expose one or more ActiveX controls that you must register. To use the test add-in for ICustomTaskPaneConsumer, you can either rebuild the add-in, which registers it, or simply register the add-in assembly that contains the managed ActiveX control. You must also be sure to rebuild or re-register the shim, so that the shim registration overrides the add-in registration.

Managing custom task panes across multiple documents in shared add in for office 2007 using .NET

I see a lot of articles on this topic but all are related to VSTO. But I required this for shared addin. I followed MSDN to create custom task pane using shared addin. It works fine but when multiple documents are opened then it appears only for the first document. I have implemented to show document wise custom task pane.
