How to create two application node-red in one computer

Hi ,
i wan't to create two applications node-red in my PC for two different users ,
How i can do that in details please !

Thank's

I you are happy that the two instance of Node-RED are always the same version, all you need is something (a script) to start Node-RED twice. In at least 1 of the instances, you will need to pass the userDir parameter to point to a different folder than the default.

If you need to cater for different versions of Node-RED or want to keep everything self-contained. Check out my alternate installer on GitHub.
