acrobat pro dc serial "not valid"

[Talino1549]

I have acrobat Pro Dc version on CD. Trying to install on my new laptop  but it won't accept my  serial number it says that it's not valid. I have the serial number on the receipt and on the box. Do serial numbers expire  or do I  need to re register my software?

Hello

It would not have to expire, perhaps because it was active on a machine before, you can enter your email account at Adobe.com or in the LWS to request support with this. Check the you followed links.

Acrobat DC does not require a serial number. It's a subscription based license that is tied to a specific Adobe account.

Are you sure you're installing the correct version?

I think I do because it's an older version 2015 and  I purchased it in 2017.

That's possible. Confusingly, older versions of Acrobat without the subscription-model (so-called "perpetual license") were also called DC... Either way, you must use the correct installer for your serial number for it to work.
