I purchased Adobe Lightroom 4 from amazon and lost my key code. I've never installed the software so I don't have the key code registered to my Adobe ID. I have proof of purchase from Amazon.com but don't know what options (if any) I have? Any insights or thoughts would be great!
I think your only hope would be to contact Amazon and see what they can do for you. Adobe no longer supports or sells Lightroom 4 so I suspect there isn't much you would be able to get from them.
