I currently have SW 2011 with a HUL on my home machine. I have just upgraded computers, and I want to install 2012 on the new machine. When I try to install 2012 on the new machine, it tells me that the serial number is incorrect. I am using the same serial number as the 2011 install. Is this correct? Or do I need a new serial number? I don't want to transfer licenses, until I know that SW will install correctly on the new machine.
