Sandboxie and Dota 2

[ZaksSaFita]

Hi guys,

Used to be able to run two instances of dota 2 with sandboxie a while ago. Now that i want to do it says launching and goes back to "play" state on steam.
Is there a way to launch two dota 2 games now or did Valve made it not work?

Thanks in advance for help.
And sorry for bad English.

3 launched as Application Compartment (NoSecurityIsolation=y) - "PLAY" didn't stick otherwise.

2 Sandboxes, 1 Steam account: all but one at REGION select: "Lost connection to Steam", which disables FIND MATCH.

2 Sandboxes, 2 Steam accounts: all at FIND MATCH give VAC message, and cannot proceed. You're on your own (AFAIC).

So that means cant open two Dota 2 games to play arcade mod.

Update: moved back to version 1.12.9 and works normaly.
