New Computer

Hi,

I just got a new computer and trying to transfer my license from the old computer to new.  I deactivated my license on the old computer and then went to install SolidWorks on the new computer.  However slightly after I ended my serial number I get an error

It is true that my subscription expired but how do I install this on the new computer now?  Do I need to uninstall SolidWorks on the first computer as well before it will let me install on this one?
