Autodesk Product Keys The serial number and product key for your Autodesk software can be found in a variety of locations, depending on how you obtained your product. Note about serial number visibility in Autodesk Account: Only account administrators, such as Contract Managers and Software Coordinators, and Named Users with assigned software benefits will see serial numbers in Autodesk Account. You are the account administrator if you purchased a software subscription using your Autodesk Account or were assigned the role of Contract Manager or Software Coordinator by your company. If you do not see the software you wish to activate in your Autodesk account or see the message "Contact your admin for serial numbers," you need to contact the contract administrator. Only an administrator can assign you as a Named User or End User and give you permissions to download and activate the software. Serial Numbers do not appear on software packaging for Autodesk software versions and newer.
That said, you do have to build a furnace to smelting ore into ingots. Build a screwdriver early on - it is useful to change the orientation of steps, blocks and other objects.
Along with pickaxes, shovels and swords, another very useful (and Minetest specific) tool you should build is the screwdriver.
