Lightroom 5: how to re-install on new MacBook Pro?

Thank you so much Pattie, Ned and John: so very helpful!

Malcom,

When you no longer need purchased Adobe software on a computer or you wish to move it to another one, you should deactivate the software. See this link: how to deactivate software. Installation rules will let you install the software on two computers of the same platform (both windows or both mac) but you are limited to running it on only one at a time. If you have only installed it once, you should be able to install it on another computer with the same operating system.

If you want to install it on a new computer but you have already installed the software twice (and you don't have access to your previous computer or you upgraded your computer's hardware, replace a hard drive, upgraded your operating system, or reformatted your drive before deactivating your software), you can ask Adobe Support to help you deactivate the software from the machine. Just have your serial number or Adobe ID ready, and then contact support.. Then you can install the software and enter your serial number to re-activate the software.
