Creative Cloud Desktop App

Adobe Creative Cloud installation failed with Error 22

Error code: 22

Adobe Creative Cloud apps cannot be installed on a case-sensitive file system. Error 22 appears when the target drive is formatted with a case-sensitive file system (such as a case-sensitive APFS or HFS+ volume on macOS), which is not supported by Adobe's installer.

Observed message

Error code: 22

Why it happens

The installation target drive uses a case-sensitive file system, which Adobe apps do not support.
On macOS, the drive is formatted as APFS (Case-sensitive) or HFS+ (Case-sensitive).

How to fix it

Change the installation destination in the Creative Cloud desktop app to a drive formatted with a case-insensitive file system.
If the system drive is case-sensitive, reformat it as APFS or HFS+ (case-insensitive) — note this requires a full system reinstall and data backup.
Install the Creative Cloud apps on a secondary, case-insensitive drive if available.
