Hi, could you please explain how to set NSSM to run two separate instances at boot in windows 10?  
I've tryed several ways without success. Till last week I just run node-red at boot with NSSM without problem, now I need to run a different node-red instance on the port 1881. By the command line it's not a problem (node-red -p 1881 -u c:/....", infact I created a dedicate folder that has been populated with it's own files as suggested on the previous posts. I even modify the settings.js file inside this folder changin the "uiPort: process.env.PORT || 1881"  
But I'm not able to make this service running.  
I configure it as following:  
Path: C:\Users\1\AppData\Roaming\npm\node-red.cmd  
Startap directory: C:\Users\1.node-red-two  
Arguments --settings "C:\Users\1.node-red-two\settings.js" \> "c:\temp\node-red\node-red-two.log"  
for what I've understood the problems is the node-red.cmd file called inside the path.  
Could someone please help me? Should I create a new path? Which files should I copy in and how modify them?  
Many thanks
