I wanted to give back to the community with my multiboxing method. You need an additional account per instance.

Make sure you allow multi boxing through your battle.net app before you start!

1. Go to your d2r installation folder, make a copy of the folder for each game/instance you plan to run.

2. download processexplorer from microsoft or processhacker, whichever you prefer.

3. launch the Diablo II Resurrected Launcher from your install folder.

4. Input your account information and click play.

5. run process explorer as admin. Find the process handle **\Sessions\1\BaseNamedObjects\DiabloII Check For Other Instances** and kill the process.

6. go to your next install folder and run the second Diablo II Resurrected Launcher from the next install folder.

7. Login with your second account.

8. If you did everything right there should be a play button on your bnet launcher for your second account.
Thanks and enjoy.

Question, in dwights voice.

Do I need multiple cd keys

yes, edited. Thank you

Thank you! I will be looking into this at some point. atm running two real computers, but i think i want them under the same roof.

Thank you. Will try. Running VM with gpu passthrough atm.

Thank you, worked great, tip to use the "find handle" option to find the thing to close

Yeah, will edit more in a bit.

Does it run choppy even on legacy graphics like ISboxer?

No its runs fine for me, but have to redo the process if a client crash

You tried OPs method and both windows run good? Will need to try that out then if so
