There is no "Autodesk Expert Elite" software to download. The Autodesk Expert Elite program is not a product or a tool. It is an invitation-only recognition program for top community contributors who help other Autodesk users (similar to an MVP award). You cannot download, install, or buy it.
If you tell me (e.g., AutoCAD, Revit, Maya), I can point you to the correct free or trial download link from Autodesk’s official website. free autodesk expert elite download
