Let me add to this:
Our company merged with another company. They have a few adobe products, I was inquiring how can I find out what is the remaining licenses are left on various proucts? Should I register them?
Not automatically or online, if that's what you're asking... Generally for most customers you are allowed up to two license activations per product - and you can contact Adobe customer service (by any means) and they will tell you how many are left, or reset your activations to zero for you. The software will also tell you if you are over your limit when you install it anew.
