How to install previous version of Illustrator v28

​@Bobby Henderson ditto, I am using a MacBook that has Illustrator 28.0 and was undecided if I wanted to use the OpenCore Legacy Patcher for my Macbook so that it can run Tahoe and the other latest versions… than thought, I can just add the newer apps on my wife’s PC instead. Problem solved. Except, I am not a big fans of PC! This is one of the reasons why I have ‘Auto-update’ turned off on my MAC and her PC as well because of all these weird bugs. 

I do see the app on my MAC, but I don’t think the 3 gig app would actually work that way by dragging it to the Cloud and letting someone else use it—even if they legitimately purchased it. Adobe Support should be able to provide you the legit downloadable link. 

If not, you could use Wayback Machine? Maybe not as secured...

I would try contacting Adobe’s customer support and see if they could help and give you a download link to a version 28 installer. The installers in the Creative Cloud app go back only one version. I’m trying to protect an Illustrator 28 installation on my setup due to a different issue with versions 29 and 30.
