I'm starting a project for AutoCAD and I need AutoCAD 2019 .NET and OpenARX 2019 libraries. But the installers I downloaded from AutoCAD website show me an error [Images below].
As far as I know, they use .NET Framework 4.7 which I'm installing on my computer right now among the basic installation for .NET desktop development.
Is it possible to make this backwards compatible? what's the correct way to do it?
Thanks in avance
