I recently received this question after a customer installed CC 2015, and unintentionally removed their CC 2014 apps.
“How do I reinstall previous versions of my Creative Cloud apps? They don’t show up in the Previous Versions section of the Apps tab. I also filtered the Find Additional Apps section to show all apps and I don’t see them. Where did they go?”
First, I should point out that the Latest Versions & Previous Versions sections within the Apps tab show what’s currently installed on your machine.
To install previous versions of Creative Cloud apps, you’ll start by going to the Find Additional Apps section of the Apps tab within the Creative Cloud Desktop App. Select the filter menu, and change the All Apps setting to View Previous Versions as shown in the image above.
Once the filter has been set, you will see a list of Creative Cloud apps. Clicking the install button will reveal the versions list, and you can reinstall any previous app version available.
