Word 2007 add-in for a custom ribbon - ribbon not visible in the saved document

I have a requirement where I need to have a custom ribbon added to the Word 2007 file which will be populated from some items. I created a add-in using this and pressing F5 opens Word file contains the newly added custom ribbon. But I save tha开发者_开发百科t word file and open that again and It does not have that newly added custom ribbon. I am sure I am missing something here.Could anybody throw some light?

I save that word file and open that again

Are you opening it again outside of the Word instance running from Visual Studio? Your add-in might only be available when you're debugging the project.

Check if an entry for your add-in exists in the registry, under:

HKLM\Software\Microsoft\Office\Word\Addins\.

If no entry exists, I've found that the easiest way to deploy a VSTO add-in to your machine is to create a setup project for it in Visual Studio.
