Operating system guest accounts are not supported | Creative Cloud 2019 or later
Creative Cloud 2019 or later versions do not support operating system guest accounts. Use regular accounts instead.

Issue

Creative Cloud version 2019 or later apps use several operating system security features to ensure that your apps and subscriptions remain safe and secure.

Guest accounts on modern operating systems, such as macOS and Windows 10, are restricted and do not provide write permissions to areas required by Creative Cloud apps. Also, all files created by a guest user are deleted once the user logs out.

Installing and using Adobe Creative Cloud apps on guest accounts is not recommended or supported.

Resolution

Adobe recommends that you use regular user accounts to install Creative Cloud apps.
