Welcome to the forum.
Can you please let us know more about what you are attempting to do?
Are you trying to download the trial, or a purchased version of PrE to the second computer?
Have you downloaded the installation files, but it will not install on the second computer?
What are the specs. of the computer, that is having the problem, and also, what are the specs. of the computer, where you have PrE installed?
Do you get error messages?
Many more questions, but, for now, I will limit mine to
When you say
elements wont let me download on second computer
what is the specific wording of the message that you get presumably from Adobe when the disallow occurs?
We will be watching for your full details on the matter.
>wont let me download on second computer
Do you mean INSTALL, or download the install file from the the Internet to your computer?
