Hi, Is It possible to launch multiple instances of Postman app from the same host? The scenario is the following. Several testers of a same team access a remote Linux machine where Postman is installed. They login using the same Linux user account, so that each of them will launch an instances of Postman under a same Linux user. However the attempt to run a second instance when a first one is already opened fails. The testers should be able to work concurrently so that each can run some part of a shared collection. Any help? Thanks ---

Indeed my original problem is that if two testers run 2 instances of Postman in the described conditions, the last one gets back this error “main error “WindowManager~getSharedWindow: Shared window is not available”” and the app fails to open. If any has a solution to this root cause, it’s appreciated ---

Hmmm you can open multiple windows of a single Postman instance. ![49%20PM](https://us1.discourse-cdn.com/getpostman/original/3X/3/7/370102e20d755b64d09aaf50ae34a748631f20a5.png) This is in Mac, I would believe we’d have a similar option in Windows. Also if you want to work on shared collections at the same time, created a Postman team would be easier. There is a free tier and you can have 25 shared requests for free which will sync across a team workspace. > **[Collaborate in Postman | Postman Learning Center](https://learning.postman.com/docs/collaborating-in-postman/collaborate-in-postman-overview/)** > > Postman is a collaboration platform for API development.

It’s now available in Windows too, I’m on version 7.36.5. ![image](https://us1.discourse-cdn.com/getpostman/original/3X/7/2/72436c664469ad3bfba23ada040d2c58961bd27d.png) ---

Ok but how do we run two instances using different logins? The moment I log out in one instance, it logs me out in the other too. Actually all I really need to be able to do is transfer my workspace (including environments etc.) from one login to another.
