Temporary activation expired | CS3, Acrobat 8


“Temporary Activation Expired,” error is encountered when you try to activate Creative Suite 3 and Acrobat 8 application.

Temporary activation expired


The licensing information is stored in a database file named cache.db. This error occurs when the cached licensing data from previous Adobe software installation conflict with the new installation. Removal of the data file allows a successful installation of Creative Suite 3, and Acrobat 8, without a request to activate the software.


Removing the cached licensing database file (cache.db) affects the licensing of other installed Adobe software like Creative Suite, Photoshop Elements, Premiere Elements, Acrobat, Creative Cloud applications and more.

Follow the steps below to resolve this issue. Make sure that you have admin privileges on your system before trying the steps.

  1. Uninstall all Adobe software before removing the cache. db file. To uninstall the software, run the Adobe uninstaller from the following locations:

    • Mac OS: In the Finder, navigate to Applications > Utilities > Adobe Installers.
    • Windows 10, 8, 7, or Vista: Choose Start > Control Panel > Programs and Features.
  2. Download and run the Creative Cloud Cleaner Tool to remove any remaining licensing entries.

  3. Navigate to the cache folder and manually remove the cache.db file. 

    Mac OS: /Library/Application Support/Adobe/Adobe PCD/cache/
