TeamViewer 'Console' - Manual automated update

 Some context may help...

We use TeamViewer to remotely support our users.

I don't know what the app used to manage / connect to others is actually called - So I call it the 'Console'.
'Host' is the client installed on all of the computers we support.

NOTE:
The 'Console' installs to this folder: C:\Program Files\TeamViewer\TeamViewer.exe
The 'Host' installs to this folder: C:\Program Files (x86)\TeamViewer\TeamViewer.exe


The console also acts as a 'Client' - So having the 'Client installed on my home computer, allows me to remote connect to my work computer and WFH easily... And conversely, from work, I can easily access my home computer, if needed.

From home - I kept running into (infrequently) not being able to connect to my work computer...
The computer would show, but as 'offline'...

1. The updated file / installer would download...
2. That installer would shutdown the current TeamViewer...
3. And then the installer would fail to complete

(I think its ESET AV - but I am not going to try and explain this to my boss who controls that config - to much work - He turns everything into an argument.)

The end result - Teamviewer is not running, so I cant connect to the work computer...

I put together the below PoSh Script to get past the above problem...
It is a scheduled task that runs at 3AM every day - It takes about 6 minutes to complete
It downloads the most recent version of the Powershell 'Console'...
Compares the 'version info' of that download, to the 'version info' of the currently installed...

If needed, it proceeds to kill Teamviewer, and run the install from that download.
It presents a pop-up window beforehand with a warning, and other useful info...

After that completes, it restarts TeamViewer.
Verifies the downloaded vs. installed versions.

Even if no updates are needed - Regardless, it checks to see if TeamViewwer is running and if not will (attempt to) restart it.

Additionally, it logs all of the pertinent info (currently set to only hold 50 lines)
