The best way is to create a Setup for your program
You can do this using Package & Deployment wizard in VS6.0
Programs-->Microsoft Visual Studio--Microsoft Visual Studio Tools-->Package & Deployment wizard
Just give the path of your project file and the location you want the setup.
You can then use the setup to install DLLs automatically in required machines
