When you register your Adobe Acrobat 9 product, the serial number is stored in the Windows registry. If you want to change the value of the registration, you must edit the Windows registry. This is accomplished using your Windows registry editor. The registration value is used when you update and patch the software. Adobe does a check on your system to ensure the product is valid, and you registered it with the company.

Skill level:


  1. 1

    Click the Windows "Start" button. Type "regedit" into the search text box and press "Enter." This opens your registry editor.

  2. 2

    Navigate to the "HKEY_LOCAL_MACHINE\Software\Adobe\Adobe Acrobat\9.0\" key in your registry. In the centre detail window, double-click the "Registration" key. This opens a configuration window.

  3. 3

    Type your new registration key into the "Value" text box. Click "OK" to save your settings. Reboot your computer for the registry settings to take effect.
