Yes, you need to have two seperate installations. Why? Because each Integration Server will be accessing things like config files and package directories at their own time and the config files store, among other things, which ports the servers run on.
So the best bet is this:
Install the first Integration Server.
Start the first Integration Server.
Open up the admin pages and change the first server’s primary port to 5556 [NOTE: you will then have to go to this port to get to the admin pages]
Now, install the second Integration Server in a new directory.
Start the second Integration Server.
Open up the admin pages (on port 5555)
If both servers are up then you did everything right!
