We have a network license of AutoCAD 2013 installed on a couple of machines, due to the conflict in a standalone install of Fabrication CADmep 2013 we need to move the AutoCAD 2013 license from Network to Standalone. We have the standalone license number and product codes. We just need to understand if we have to uninstall the network autoCAD and re install or is it possible to assign the standalone license number to the current install.
Nope, you will have to reinstall as stand-alone so that it properly licenses. You can try the reg hack but it'll probably cause more trouble than it is worth. A clean reinstall will get you where you need to be.
