Do purchased individual products have the ability to be upgraded? If so then the updates are limited to time or not? In this case, the information is missing or not very clear.
You can receive updates for a individual item ( same version )
but upgrades to a newer version you will have to re buy and get
a new Lic.
If you have an Object Desktop subcription ( annual subscription yearly renewal )
then you receive both updates and upgrades ....
