I'm completely new to Node Red and I'm having a bit of trouble managing palettes (Node Red is running locally). While trying to install node-red-node-arduino it fails and I'm left with the following log, could someone shine some light as to what the issue is?

Hi  
To add to what @hardillb is saying, you need to install build tools first. From an elevated command prompt...

```auto
npm install --global windows-build-tools

```

... Then try installing the modbus node again.

NOTE: it can take quite some time to install build tools and might appear frozen, please wait it out.

Ran it as administrator in Powershell and got the following:

PS C:\WINDOWS\system32\> npm install --global windows-build-tools

Did you leave it to complete? It has to download a significant amount and may take a long time if you don't have fast broadand.

Left it for like 2-3 hours and nothing more came up, but I have to admit that it did not look like it was finished.

It isn't finished till it comes back to the command prompt.  
Please don't post screenshots unless necessary, copy/paste text instead.
