1)copy paste you diablo III folders inside the program files folder Directory as many times as the clients you wanna run
2) for each folder make the same amount of shortcuts on your desktop
3)run them normaly in order to open the d3 launcher in order to initialize
4) add -launch in the properties
5) you are done
