I have Adobe Acrobat DC ( 32 bit ) and a license key (xxxx-xxxx-xxxx-xxxx-xxxx-xxxxx ). I looked under Help\About and only saw update. I was looking for activate since the online licensing help said that's where I could put the license key. Is there a free trial I can download that works with this type of key ?
Make sure you downloaded the right product, which won't be Acrobat DC, that's for subscriptions only. It will be Acrobat 2020, 2017 or 2015.
