PInvoke runtime error when deploy Word Addin

I'm creating a Word Add-in which depends on an unmanaged dll that I wrapped with SWIG ("Simplified Wrapper Interface Generator"). Essentially SWIG generates a managed c# wrapper of an unmanaged dll that uses P/Invoke. The add-in runs as expected on my machine when I use the "Register ADX Project" feature. However, P/Invoke fails with a runtime exception when I deploy the addin to another machine using the Setup installer project. I made sure to add the unmanaged dll to the Program Folder in the Setup project and I've verified that the unmanaged dll is alongside the dll of my addin (in "c:/Program Files/company/addinname/" where the addin is installed). Any ideas why P/Invoke is failing? I'm not using either the adx loader nor the shim (to avoid having to sign my assemblies). Could this have something to do with it? Why isn't the addin's installed directory in the search path for P/Invoke?

Thanks in advance, Dustin

Hi Dustin.

Where the unmanaged dll is located on the development PC?
