Using Custom File Manger and Defining Path?

I want to use Dopus with a program, they allow custom file mangers for the application. My goal is to use Dopus with the program so when finding a file > I click on the file and it open a new tab or current tab in Directory Opus. It ask for "Path:". When doing so, do i point the program to the directory opus exe file? Now I have tried that and it doesn't work, I get an error saying "go back, "abort" or "try again".

Wanted to know if you knew anything that could allow me to use dopus to open new tabs.
