In several years, Autodesk has stopped supporting some of their 32-Bit software. Such as Revit, Inventor, and 3ds Max. Autodesk finally decided to stop providing AutoCAD 32-Bit. We all can see this coming because 32-Bit has become less popular and the most operating system is 64-Bit now. And don’t forget the benefits of the 64-Bit system over the 32-Bit system.
You can still use AutoCAD and AutoCAD LT 2019 or older if you need a 32-Bit system. However, Autodesk won’t provide 64-Bit for 2020 version.
