Re: I have reinstalled Acrobat Pro 9 following a hard drive re format. It opens just fine but does not recognize my serial number. My computer is running Windows 7 64 bit

Hi 12msonti,

Please try the following:

• Windows:  \Program Files\Common Files\Adobe\Adobe PCD
                      \Program Files\Common Files\Adobe\caps\caps.db

Launch Acrobat and enter the serial number and check.

Regards,

Rave
