Free Creative Cloud Tools

It is not "free access". The program is for schools who subscribe to Creative Cloud in their labs to extend that access because students can't get to the labs. See details here:

If your school is part of this program, then talk to your IT department. They need to fix it at their end.

Adobe is providing "free" access to its Creative Cloud apps only if you are in education as a teacher or student. For institutions that give students access to Creative Cloud apps through on-campus computer labs, Adobe is enabling those students to work remotely for 60 days through a temporary "at home" access. This has to be set up through the school.
