I downloaded the trial version of Photoshop CC and used it for a while and have decided to get the paid version. After giving my credit card information, it wants to download and install Photoshop CC. Am I supposed to let that happen? I thought I would just get a registration code.
No, you do not get a serial number with Creative Cloud. Simply download,install and sign in with your Adobe ID and password that you gave your credit info to.
Do I need to uninstall the trial version of PS CC?
Yes, before you install the download.
