I had to wipe off and reformat my MacBook Pro - saved all the info from Lightroom 4 - and want to reinstall it. How do I do that?
Download LR 4.4 here:
Adobe - Lightroom : For Macintosh : Adobe Photoshop Lightroom 4.4
Install it, re-enter your serial number, copy your catalog over and ideally put all your photos back where they were otherwise you'll have to redirect Lightroom to their current location.
