I recently transferred from Mаcbook Pro to Macbook Air using Migration Assistant. When I started Elements for the first time on MBAir, it said that something was wrong with the installed Elements and I should reinstall. First I used the Air's ability to use another computer's DVD drive (it has none itself). The installer failed. Then I used an outboard USB DVD drive, but the installer failed again. I then deleted the Elements on the new computer and tried to install again using the disk in the USB drive. It failed. If there is anybody there who can help, i'd very much appreciate it!
You've posted on the 'Digital Editions' subforum by mistake. Try the forum for Elements. Good luck with more info there.
