Updated October 2023
Adobe typically allow users to install previous versions of Adobe Illustrator. At the time of writing (18 October 2023), the current Illustrator version is Illustrator 2024 (v28). Through the Creative Cloud application, it is possible to install this and Illustrator 2021 (v25.x).
By request, Adobe also provide installers for Illustrator 2019 (v23.x) and earlier however, Adobe no longer provide installers for Illustrator 2020 (v24.x), either via the CC application, or as stand-alone installers. We have checked this status with Adobe (support and engineering) and can confirm this policy will not likely change.
If you already have Illustrator 2020 installed on your computer, it should remain functional however, if you uninstall it you will not be able to reinstall it.
Following this development, Astute Graphics have had to cease support for Illustrator 2020 plugins. They will remain available via the Astute Manager, but their operation cannot be backed up with any technical assistance. This is because Astute Graphics is, itself, unable to install Illustrator 2020 on a full range of test environments.
We thoroughly recommend that all users update Illustrator to 2021, or above. These versions of Illustrator are also proving to be more stable.
