When I initially install Adobe Acrobat Pro DC. It ask me for Adobe ID (I don't have one), so I install a/as trial version thinking I can register or activiate later like CS4, Acrobat 7 and 8
I have since created a Adobe ID and try to register or activate or get the serial number, but no luck
I have unstall the software and try re-install it, but it is stuck at need serial number
Please start your own thread in the correct forum. This is the Lightroom forum not the Acrobat forum or the Download and install forum.
