Ran the Repair Tool. It ran successfully so I then ran dotNetFx40_Full_setup.exe to try to re-install it, but it failed. Log is shown below.

Clicked on the Next button from Repair Tool install and it came back saying "The tool is unable to resolve the installation issue on your computer". It generated a bunch of logs and put them in a .cab file.
