Required permissions for Photoshop

When running Photoshop from a non-Administrator account, Photoshop requires read access to some system-level folders and read/write access to some user-level folders.

Note: A user account with full administrative rights is required for installation.

Read/write access is required to the root folder of any non-boot drive that is specified in Photoshop's Preferences as a scratch disk.

Read/write access is required to any folders into which you've saved files.

Read/write access is required to these user-level folders:

• Mac OS: The User's Library folder. To access this folder, see Can't see user library files in Mac OS 10.7 and later.
• Windows: The User's AppData folder. This folder is located under the Users\[Username] folder.

Read access is required to these system-level folders:

• Mac OS: The System Library folder and the Application folders.

Note: The System Library folder is different from the Users' Library folder.

1. Choose Go > Computer

2. Select Macintosh HD > System > Library.

• Windows: The Program Files folder (for 64-bit program installations), or the Program Files (x86) folder (for 32-bit program installations).
