Re: How do I re-install Elements 10 from an old computer to a new computer? I already deleted it off the old computer and didn't deactivate it. Now my serial number won't work.

I have the boxed version. And it is good on two computers. One is on my work computer, the other one is on my home desktop. I deactivated elements off the old computer just now and re-installed on my MAC, it says the serial number is invalid.

Thank you!
