https://forums.autodesk.com/t5/autocad-forum/serial-number/m-p/5538280#M337600 thank you very much for your help.<BR />I was having difficulty with the log in at the subscription center.<BR />I now have the SN.<BR /><BR /><BR />Next question: I'm the only person who uses this software. Is it possible to place it on 2 non-networked machines? I was thinking about my desktop and my laptop. Actually I could probably get them networked very easily for a floating license. However, is there some kind of USB-type hardware key that I can insert into the computer I'm using to allow it to work only on that one machine?<BR /><BR /><BR />Thanks again.<BR /><BR /><BR />John Thu, 12 Mar 2015 15:09:35 GMT Anonymous 2015-03-12T15:09:35Z
