I've got a generic QR code scanner which basically behaves like a keyboard. I'm trying to get this qr barcode input when a barcode is scanned.
Does anybody how to get this to work on Windows?
I tried that but it doesn't allow me to install it.
what doesn't allow you to install it?
How are you starting node-red? from a command terminal or powershell? Could you copy and past that error from there?
I start node red via the task scheduler on start-up "start a program" "C://.../node-red.cmd"
for now, just run it manually (ctrl+r and then type "node-red") so we can see the complete error output.

You don't have the Windows build tools installed.
Easiest thing to do is to grab the latest copy of the LTS release of Node.js for Windows and install it. It should ask if you want the build tools, accept that option. Restart node-red and you should be good to go.
