Visual Studio Installer Problem with assembly

I am hesitant to ask this question because I feel like it has been answered I just can seem to find it. I have a program that runs fine in Release, however I use the VS Installer and actually install it tells me it can't find the file. I try a bunch of different things to make it work and still nothing. At times I think I made things much worse.

I can build the project find. It has no problems running in VS 2010. I also have no error's when I build the installer. The file which is the assembly a exe, that is basically acting like DLL. I install the program file, and the program loads fine. When I can a specific function I run into the the missing开发者_开发知识库 could not locate file or assembly message.

I removed the reference and downloaded another copy of the library. I added the reference again and made a new install project.
