Multiples Roblox Instances Not Working

same problem here 

@Astronemi

That did not help. :(

doesn't work either 

@Tenkin

I fixed it by using synapse X to get off of the beta roblox version.

I get this as well, only after trying to connect a 5th account though. The first 4 work fine.

@Common can you explain me how you did this ? and did you buy synapse or is there a free version somewhere ? 

@Tenkin

I've had synapse for a few years, and yes I bought it. Basically, I launched synapse, and it told me I was on a beta version. It said if I enabled auto-launch it could make it not on beta, so I did that. Then, I just had synapse open, had multiple-roblox open, and it all worked fine! :)

@CrazedPilot

I use 5 accounts and it works fine for me. Weird

Hmmmm

@Common Is that with the beta version of roblox or with Synapse's revert?

This is with the Roblox desktop beta app yes 

@CrazedPilot

I was using 5 accounts on both.

Maybe Roblox changed the mutex.

Suggest writing your own. it's just 3 lines of code.

new Mutex("ROBLOX_singelton")

or something.

Anyways, it works. probaly ur PC or some

I also can't get Roblox Multiple Instances to work.

How to reproduce the problem:
1. Open Roblox Multiple Instances

2. Launch a game from account #1 and wait until the experience is fully loaded up

3. Log out from account #1 and log in using account #2 then launch the experience from account #2

4. The experience window from account #1 is closed and replaced by that of account #2

Let me know if any of you are having the same issue

Is this because of the latest Roblox Launcher update?
