Where should VSTO-developed extensions be installed?

I am building an extension ribbon for Excel. Besides the ribbon DLL I will have a data access DLL and a .sdf (SQL CE database file). In which directori开发者_开发知识库es should they be installed? Is there a best practice for deploying this project? It will be used at several sites around the country.

Generally, I install vsto addins just like any other addin or application. I have the installer create a \program files\MyCompany\MyApp folder, put the dlls, and the addin's Manifest and config files right there. Maybe create a few subfolders to store other info. then Register the addin and point to that location.
