What version of Photoshop Elements and Premiere Elements?

stuartd57997370  wrote I had Elements and Premier Elements installed and then had windows problems.  Had to reinstall Windows and lost all my programs including Elements and Premier elements.  I reinstalled the two programs using the Serial Numbers I used for the first installation.  What happens if I have to reinstall again?  Or want to install on a second machine?  Will the Serial Numbers work again?

If you installed on the same computer and hardware, I believe you are safe. The license is linked to your hardware. If you changed your drives for instance, the activation would be lost; then you'd have to use the 'chat' option in 'customer care'. Only Adobe can solve the common situation of a broken or stolen computer.
