Where can I find my product serial number/licence key in the installed and working Adobe Acrobat Pro?

[chintant48166306]

I have acrobate pro for mac. Bought it in 2012-13 from some online store and was provided the software and a licence key. I never registered the key with my adobe account considering it of no use. Software was updating and working perfectly until the last version of Adobe reader 11.0.20 got installed in my mac. Now it is not allowing me to edit any pdf without sign in to the account, To edit a pdf it redirects me to web browser to purchase monthly/yearly subscriptions. I tried to contact customer care but without serial key / licence number they were not able to help me. Where can I find my licence number/product serial key in the software? How can I roll back to the last version of adobe reader which works offline too?

Don't try and use Edit PDF in Reader, you haven't paid for that. What do you get when you start Acrobat (NOT READER)?

Sorry, I understood my mistake.

Like an idiot I was opening and trying to edit files on adobe reader from last 3 hours.

I just opened Acrobat pro and it is working perfectly with all editing options.

Where can I find serial number of my Acrobat pro in the software to register it with Adobe ID?

This is the screen shot of what I see when I open Acrobat Pro. How to add this software to my adobe id if I don't have the serial number. May I find my product serial number somewhere in the software?

Why do you want to use it with your Adobe ID? Just use it as you always did.

Sorry just reread your question. You can't get the serial number out. You would have to find the source (e.g. an email) if you didn't register it initially.

Understood, I'll try to find it in old emails if available.

Thanks for your help.
