Offline Activation for 6.3.2

Online activation is not an option .
I have been using version 6.3.2 which I enabled using the offline activation code last year. I have since moved to a new desk with a new workstation. I was able to install version 6.3 to my new workstation from our enterprise repository However; since offline activation is no longer available it is useless.

I’m not trying to use Version 7 which requires a license, I simply want to use a version that has always been free. Again, Online activation is not an option .

Is there a way to get the old offline activation code off one machine and reuse on a new install? Or… Is there any way to get a new offline activation code for the older versions of Katalon Studio?
