Solution 1: Check the log files folder

This issue can occur when Adobe products are unable to access or write to a log files folder. Check the folder listed below to ensure that it exists and your current user account has write permissions to change its content.

  1. Windows:

    • Access %USERPROFILE%\AppData\Local\Adobe\Creative Cloud Libraries\Logs from the search field in the Start Menu or from the Run command
    • Confirm that the folder exists and you have write permissions for it.  

  2. Mac OS:

    • Access ~/Library/Logs/Creative Cloud/Creative Cloud Libraries using the Go to Folder command.
    • Confirm that the folder exists and you have write permissions for it.

Solution 2: Change the following folder content

  1. Close any open Adobe products such as Photoshop, Illustrator, Dreamweaver, or InDesign.

  2. Move the content from the folder listed below to somewhere else as a backup (in a folder on your Desktop for example). See the path below for the folder location by product.

    Note:

    You need to select the product executable directly and Ctrl+click it to use the Show Package Contents command to access the product directories listed below.
