Hi,  
i tried to add the node dmxusbpro as well to a windows pc and also to a raspberry. Fails in both machines witch a lot of errors reported.

I looked int github and found the following:  
Hello! I'm reviving this thread with a solution that worked for me on Ubuntu 18.04 with NodeJS v15.14.

Clone the repo  
In the file "package.json" replace the following lines

```auto
"dependencies" : {
        "serialport" : "^6.2.0"
    },

```

for the following (I use serialport version 7.7.6. Change it to whatever version your using)

```auto
"dependencies" : {
        "serialport" : "^7.7.6"
    },

```

Build locally with

`npm install ~/path/to/repo/node-red-contrib-dmxusbpro`

Voilà!

The thing is: i'm not a 'programmer' who is used to work with github. So can anybody please give me help how to do that on a windows machine?

Kind regards

Alexander
