Sup guys
This is a short tutorial on how to run a copy from Steam if you already play through Bnet
went through some trouble shooting today trying to run both simultaneously
I wish it would have been as simple as clicking play but it wasn't
- first you need Process Explorer
- make sure you run Process Explorer as admin
- now you can click play on one of em (doesn't matter if you launch from Bnet or Steam)
- once the game is launch you need to select D2R and be able to see the handles like so :

- then the only thing left to do is to close Event \Sessions\1\BaseNamedObjects\DiabloII Check For Other Instances
- Run the other game
hope this helps someone
peace!
