I'm trying to deactivate some installed software on a Macintosh OS X v10.5.8.
When I launch Adobe Acrobat Pro 9, it comes up fine, but in the Help menu, the "Enter Serial Number..." choice is grayed out. Does this mean that the serial number was never entered or that it has already been entered. If already entered, how do I deactivate this copy? I did the same thing on Adobe Photoshop CS4 with no problem. In Photoshop, there was a "Deactivate" menu choice in the help menu, but in Acrobat, there is no such menu.
How can I deactivate Adobe Acrobat Pro 9?
You don't activate/deactivate installations of Adobe Acrobat. – Ramhound – 2012-03-07T19:02:10.317
Does it require a serial number? If so, how do they enforce the license, what keeps you from installing it repeatedly? – WilliamKF – 2012-03-07T20:50:27.253

@Ramhound That contradicts what Adobe states here: http://kb2.adobe.com/cps/100/1008779.html
