No sorry, I’m not a fan of installing things from the program itself. I would explain it to you, but it would be exactly the same as the routes, so there is no point.
Having version 4.8.1 framework is more than enough.
I installed .NET Framework 4.8.1 [Developer Pack]. Seems like it worked for the SDK.
Thanks anyway.
I will tell an admin to delete comments that are not related to the problem.
