Install node-red to windows server in different ports

Hello everyone, I need to install node-RED to a windows server in different ports and I can't find a way to do it. Already tried many things but none of them is working.
I did this before in linux servers and it's easy but I'm having issues with windows.
If anyone can help it would be much appreciated.
Thanks in advance!

Are you meaning multiple instances of node-red on ONE Windows Server - each with a different port number?

Or 1 Node-RED on 1 Windows Server with a port different to the default 1880 port?

Either way, for Windows Server, I would recommend

Yes, I'm meaning the first one.
It'd be perfect if I could have in one windows server different flows in port 1880, 1881, 1882, and so on.

Thank you for the links you provided, I'm going to check them.

In addition to Steve's suggestions. If you are going to use IIS as a reverse proxy, the normal approach is to use iisnode which should manage the running of Node-RED for you. This is what Microsoft use on Azure for example.

That would also give you options to use standard ports and redirect URI's to individual Node-RED instances.
