I have previously purchased Lightroom and Premiere Elements for my PC which recently died. I now have a macbook. Is it possible to get the mac software for these two programs without having to purchase it again?
It depends which version of Elements this concerns. For older versions you would normally have a license that is valid for both Windows and Mac platforms. Downloads for older versions are available thru the links below.
You can also download the trial version of the software thru the site linked below and then use your current serial number to activate it.
Be sure to follow the steps outlined in the Note: Very Important Instructions section on the download pages at this site and have cookies enabled in your browser or else the download will not work properly.
