Invalid serial number.  This is not a valid serial number.  Please go back and re-enter your serial number.

I have the original serial number and attempting to install Acrobat 7.0 professional on a new computer with Windows 7 and get this error message.

How do I get it to work?

Hi Parrotdise ,

Please refer to this article for Acrobat Pro 7 :- Error: "Activation Server Unavailable" | CS2, Acrobat 7, Audition 3

Let me know if it works.
