Change dll reference directory

Question

Hi, I want to remove the referenced dlls I am using from the directory where my .exe is and want to move them to a directory called "Dlls" and use them from there, so the directory where my exe is situated is not so crowded (I have about 9 dlls that I am using). I have added that directory in the references path in project properites, and for each dll I changed the Copy Local property to False. It builds OK, but it crashes when I try to execute it. Thanks
