Have you found bugs in the latest version of InDesign? Perhaps you’ve found this version is incompatible with another piece of software. These are just some of the reasons you may want to install a previous version of InDesign and this is very easy to do.
From the Creative Cloud App click the down arrow next to the InDesign Open button. Choose Manage and then Other Versions. You will see all the other versions that you can install. Simply click on “Install” for the version you want and it will automatically download and then install itself.
It’s also possible to have multiple versions of InDesign installed at the same time. In such a case you will see a triangle next to the InDesign entry within the CC App. Clicking on this triangle will reveal all of the versions. To open any version simply click the corresponding Open button.
