Where can you find an activation code for Adobe Photoshop CS3?

New activation keys for Adobe Photoshop CS3 cannot be legally obtained unless the software is legitimately purchased. Adobe does not sell legacy versions of their software, and does not provide activation keys for Photoshop CS3.

Users who have legitimately purchased Photoshop CS3 can obtain activation keys from the product packaging. If the software is registered with an Adobe account, the activation key is available in the account information on Adobe's website. For users who cannot find the license key in these areas or who do not own Photoshop CS3, a copy of the current version of Photoshop must be purchased. Obtaining an activation key from any other source is illegal.
