How do I install Acrobat 9 Pro on a new computer - it asks for an activation code?
1. Deactivate it on the old computer (Help > Deactivate…)
2. Install it from the original installer with all updates again. You will need the Serial Number, either during installation process or when the progamm launches the first time.
If you have no possibility to deactivate it again you should call Adobe Technical Support. They will help you.
