failed to install microsoft visual studio 2017 community

So under normal circumstances, this doesn’t appear to be a problem that many people are facing, hence the lack of support on the community forums. After installing VS 2019, everything worked as intended at home as well. I then reinstalled the 4.26.2 engine and recreated the steps I followed at work. I concluded that I must’ve had a setting or file that was tripping up Unreal Engine, so I returned home and completely uninstalled all versions of Visual Studio and all the Microsoft Visual C++ redistributables as well as my installation of 4.26.2 engine. I pressed the button to launch the VS installer, followed the Unreal documentation to properly install VS 2019, and everything ended up working exactly as intended (with no mention at all of any need for VS 2017). The Epic Games launcher itself then said I needed Visual Studio 2019 installed in order to create a new C++ project. Then I went to work and tried the same thing, not realizing that I hadn’t yet installed Visual Studio on that machine and had just recently put a fresh install of 4.26.2 on it. I even tried uninstalling VS 2017, which completely prevented the engine from creating the C++ class and kept resulting in the same error the original poster here was getting. I tried setting VS 2019 as the default compiler in the engine and that still didn’t work.

That’s when I realized Unreal was using VS 2017 to create the class rather than VS 2019. For some reason Unreal kept trying to use VS 2017 (though I didn’t realize this right away) to add the C++ class, which appeared to be working however, when VS opened I kept receiving an error saying that it would be incompatible with the version of Unreal. I had both VS 20 installed prior to this attempt. I ran into a similar problem just recently trying to add a C++ class to a 4.26.2 project.
