Creative Cloud is a licensing management application that Adobe uses to confirm that you have a license to run any of their software. Logging in to Creative Cloud allows Adobe to confirm this and then allows you to use Acrobat, Photoshop, Illustrator, or whatever else you may need.
Adobe Acrobat Pro is a product that allows users to View, Fill, and Edit pdfs even if they are not the creator. CUI offers this product to all Staff and Faculty. Students will not have access to Acrobat Pro but may use alternatives such as https://smallpdf.com/edit-pdf.
