Student and Teacher version Design Premium 5 - lost serial number

Normal retail Creative Suite can be transferred (with appropriate paperwork), and in some situations may still work, but probably more often won't. But that doesn't apply here...

Part of the deal for the reduced price of Student Creative Suite was it could not be used for a reduced price upgrade, and could not be transferred to anyone, student or not. A current student can get a discounted subscription to Creative Cloud (approx $20/month in the first year, $30/month in subsequent years, commitment to pay for whole year).

Regardless of anything else, academic versions were non-transferable. It would be virtually worthless at this point anyway so might just as well toss it.

Do you mean InDesign CS5? This version is dead. Even if you have a serial I doubt you would be able to activate it as the activation server are not any more active and no modorn computer is compatible.

If you remember the email you used to register it you can probably still find the Adobe Account and any registered software associated with the account (as long as you know the password), but that doesn't mean the software is usable.

It might well still run on an older system, but it is way out of date and to the best of my recollection educationa licensing was never transferrable.
