Trophy92 I am sorry you continue to face difficulties installing the Creative Cloud Desktop application. It is possible that your current User account is unable to adjust file permissions which could be why you have tried applying the steps but continue to face difficulties.
If you would like direct support then please contact our support team directly at Contact Customer Care. For the best assistance, I recommend our chat support. Our chat representatives can provide a personalized experience to resolve the issues you have described. I would also recommend referencing this discussion.
Finally if you do wish to proceed I would recommend trying a different User account. Unless the Administrator group's permissions have been compromised the new User account should not experience the same difficulties. You can find more details on utilizing a new User account at Troubleshoot unexpected behavior | User account-specific | Adobe software | Mac OS.
