How can I deactivate the serial number / license for Lightroom 4 so I can sell the software on?

Question

I have recently started a Creative Cloud subscription and as a result have no use for (boxed) copies of Lightroom 4 and Elements 11. I would like to deactiavte / renew the serial numbers so I can sell them on second hand to someone who can make use of them.
As I didn't 'upgrade' I don't see any issue with doing this. Please could someone assist with how I remove these two software registrations from my account.

Answer 1

I read the agreement too quickly. It first says:
YOU MAY NOT RENT,  LEASE, SELL, SUBLICENSE, ASSIGN OR TRANSFER YOUR RIGHTS IN THE  SOFTWARE, OR AUTHORIZE ANY PORTION OF THE SOFTWARE TO BE COPIED  ONTO ANOTHER INDIVIDUAL OR LEGAL ENTITY'S COMPUTER EXCEPT AS MAY BE  PERMITTED HEREIN
But then it goes on to say:
You may, however, transfer all your rights to use  the Software to another individual or legal entity provided that:  (a) you also transfer this agreement, (ii) the serial  number(s), the Software and all other software or hardware bundled,  packaged or pre-installed with the Software, including all copies,  upgrades, updates and prior versions, and (iii) all copies of font  software converted into other formats to such individual or entity;  (b) you retain no upgrades, updates or copies, including backups  and copies stored on a computer; and (c) the receiving party  accepts the terms and conditions of this agreement and any other  terms and conditions under which you purchased a valid license to  the Software. NOTWITHSTANDING THE FOREGOING, YOU MAY NOT TRANSFER  EDUCATION, PRE-RELEASE, OR NOT FOR RESALE COPIES OF THE SOFTWARE.  Prior to a transfer Adobe may require that you and the receiving  party confirm in writing your compliance with this agreement,  provide Adobe with information about yourselves, and register as  end-users of the Software. Allow 4-6 weeks to transfer. Please  visit http://www.adobe.com/support  or contact Adobe's Customer Support Department for  more information.
