One license two computers

Starting small 2-person business and purchased second computer. Can we, and how do we share our one license for both computers.  Here are the icons on the 1st computers desktop.  I am not sure if they are all part one Corel package we bought.

Corel Draw 2018, 64 bit  

Capture 2018, 64 bit

Photo-Paint 2018

Connect 2018

Font Manager, 2019

If we are able to share the one license, what are your thoughts on upgrading to the 2020 version...is it worth it or advisable?

Thanks in advance for your help,

Tom and Wendy
