I have an IT managed laptop from work and I was getting the .NET framework error when trying to install the TR ANT+ drivers. It would say that I needed .NET Framework version 3.5 or higher, and that caused some confusion for me because after downloading most recent .NET framework from MS website I got an error saying I already had the most recent version of .NET installed.
I found how to check and enable .NET framework for Windows 10!
Go to Control Panel>Programs and under “Programs and Features” there is an option to “Turn Windows Features On or Off”------BINGO!
Click that and follow the directions to enable both .NET Framework 3.5 and .Net Framework 4.8.
NOTE: My .Net Framework 3.5 was not enabled originally AND only a couple of services of my .Net Framework 4.8 were enabled. IT DID NOT work for me to only enable everything in .NET Framework 4.8. I had to enable everything in .Net framework 3.5 as well.
I hope this helps someone else with a IT managed laptop.
