Adobe Creative Cloud installation failed with Exit Code 6
Exit Code: 6
Exit code 6 is a generic installation failure. The exact cause must be determined by reviewing the installation log file for the specific error message that appears below the exit code.
Leftover files or folders from a previous failed installation attempt.
Insufficient file system permissions on an installation directory.
Corrupted installation files from an incomplete prior install attempt.
How to fix it
Check the installation log (found via the Creative Cloud Help > Logs menu) under 'There are problems with your installation' for the specific underlying error.
Remove any leftover folders from previous installation attempts in Applications (macOS) or Program Files (Windows) — for example, rename 'Adobe Photoshop CC' to 'Adobe Photoshop CC old'.
Fix folder permissions on the parent directory identified in the log error messages — this requires administrator privileges.
On macOS, also check for and rename the AdobePatchFiles folder and the Adobe folder in the Applications directory.
