Reinstalling Acrobat 9.5

[Guest]

I have Acrobat 9.5, and I am getting the "Licensing not working" error.  I have dowloaded the license recovery software, and run it several times, but it is still not working.  It tells me to uninstall and reinstall the product, but I don't have the serial number any more.  How do I proceed?

retrieve your serial number: http://helpx.adobe.com/x-productkb/global/find-serial-number.html

then uninstall.

then run the cleaner:  http://labs.adobe.com/downloads/acrobatcleaner.html

then re-install.

Which operating system are you using RB Johnson?  Assuming it is Windows I would recommend reviewing Error "Licensing has stopped working" | Windows - http://helpx.adobe.com/creative-suite/kb/error-licensing-stopped-windows.html.  There are additional solutions to implement besides the Licensing Service Update tool.
