I did install the Build Tools, but Python did not get installed because it required PowerShell Admin Rights.

So, I did the Build Tools Again in **Powershell** with Admin rights. Worked fine and Python 2.7 also got installed! **Great**!

Next I put Python.exe in the Environment path...  
Finally, I ran **npm i node-red-node-serialport** from the .node-red folder. It seemed to install fine.

I brought up my node red IDE page and the Serial Port Nodes were displayed!! **Great**!  
I wired up the serial nodes and my application is now running fine!

This was a bit tiresome and I did not have python installed with the previous version of the Serial Port nodes.

I think there may have to be some dependency install of python before upgrading the serial port nodes.

Much thanks for the help. I thought I was going to have to rebuild my entire application with a clean, fresh node red install.
