DPM update error 1720, CPU 100°C, solved

Hi, 

I have been having issues with my Dell XPS 9570 running its fans near constantly. Running HWInfo showed that the CPU was getting to 100°C. I added an external fan tray which is helping, but the problem is that this was never an issue.  A Dell tech came out and replaced the motherboard, thermal paste, processor, and fans without any noticeable difference.   

I read that there are more options to better control the fans and such in the DPM (Dell Power Manager), but when I go there to update it, I get error 1720 repeatedly.  

I've followed just about every link from Microsoft and others that I could find online performing their suggestions but have had no success. When I dig into it, it indicates a problem with communicating with the Distributed Transaction Coordinator (see screenshot below of Component Services)

The event viewer has a bunch of errors related to the DPM update and all say "The Transaction Manager is not available. (Exception from HRESULT: 0x8004D01B)"

I did see somewhere that my .NET might be the incorrect version, but I'm running the latest Windows 10 release and my .NET version is and it is 4.8.04084:

The Microsoft Store says I need .NET 4.6.1, but I am unable to install that because it is already newer.

Here was an attempt at installing .NET 4.6.1 just to try:

So, anyone got any ideas on how I can solve this problem? I haven't encountered it for any other applications and the computer is running fine otherwise. Also, yes, I did disable Antivirus and Firewall etc which didn't make any difference.  

Your help is appreciated!
