Can anyone diagnose Node-red not running on Windows?

General

I have installed Node-red on a Windows 10 PC.
Because it's thousands of miles away everything is done over Teamviewer.
If I type node-red in a command window it runs and a browser opens localhost:1880.

To run it automatically I have followed the instructions to install nssm and setup a service.
Manually I can start this service, it says it is successful but the editor doesnt show up.:

The path to the executable in nssm is c:\Users\username\AppData\Roaming\npm\node-red.cmd.
If I type that full pathname in a non administrator window, Node-red starts up (even though the nssm service claims to be running)

The startup output:

c:\temp>c:\Users\XXXXX\AppData\Roaming\npm\node-red.cmd

So nssm thinks it's doing something but it's not running Node-red.
What can I do?

Have you checked the event log for messages from NSSM ?

Maybe show us what the noe-red.cmd file contains

I have not used NSSM - but usually with those sort of service managers there are options for selecting who the service will run as and the location in which to start it - have these been set ?

Can you give us a screenshot of the NSSM config for the NR service ?

Alas the TeamViewer opportunity has closed for now, I'll try and get what you asked for asap.

I can't do that right now, but if I run that cmd file manually Node-red starts up OK so I assume it's correct.

I use NSSM to start Node Red (5 instances) automatically when PC powers up or restarts. if you need any help in debugging, please let me know. I am not SME, but can sure tell you what is the setup i have done.
