Using third party .Net DLLs (Not registered in Cache)

Question

Hi Friends,
I am developing an application which uses API from another application DLLs (.Net DLLs). And these DLLs are not placed in GAC. Normally, .Net framework looks for DLLs placed in some subfolder inside the executing assembly. But my application will be installed in different location. In this case, how can I use the DLLs which are existing outside of my executing application folder.

Thank you,
Regards,
Sagar
