If you toold about your forex robot so it is really your robot and you have source code of this robot.
If yes so you can place this robot to new MT4 (place in Expert Advisor and conpure in MetaEditor) and attach it to the chart.

-----------------

If it is not your robot so it means that you do not have source code of it, and in this case: do same and if it does not work - ask the author/owner of your robot for support.

-----------------

If it is the robot you downloaded/bought from MQL5 Market so you can install it on thesame way as you already install it on your first Metatrader inscance.
