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