Create a second instance of MT4 on desktop/VPS?

 
I have searched the forum and cannot find a simple explanation of how to do this.

I have downloaded my broker's MT4 to my VPS.

If I want to create a second, or multiple 'instance of MT4' with another desktop shortcut and separate broker account, what is the easiest way to do this? I assume i can't use the same terminal and log into another broker account.
