When you install Adobe Acrobat or Adobe Reader 7 or later on Windows, one of the following errors appears, and the installation quits:

  • Error 1402: Could not open key [key name].
  • Error 1406: Could not write value Folders to key [key name]. 

TRY THIS FIRST

Remove all previous versions of Acrobat or Reader, and then reinstall

Adobe does not support multiple versions of Acrobat or Reader on the same machine. Because Acrobat and Reader work with many products, multiple versions simultaneously installed can lead to software conflicts and errors. In addition, Adobe does not recommend installing both Acrobat and Reader on the same machine. You must have administrator privileges to complete these steps. For more information on administrator privileges, see the Windows documentation or contact Microsoft.

  1. Do one of the following, depending on your version of Windows:

    • (Windows 7) Click Start > Control Panel > Programs > Programs And Features.
    • (Windows Vista) Click Start > Control Panel > Programs > Programs And Features.
    • (Windows XP) Choose Start > Control Panel, and double-click Add Or Remove Programs.
  1. Select Acrobat or Reader, and then click the option to remove or uninstall the program.
  2. Repeat the procedure for all installed versions of the program.
  3. Restart your computer and reinstall Acrobat or Reader.

    Note: For Acrobat, reinstall the program from the Acrobat disk, or download the program from adobe.com. For Reader, download the program from the Reader Download Center. If installing on Vista, right-click the Acrobat or Reader installer and select Run As Administrator.

The following demonstration shows how to uninstall Acrobat or Reader on Windows XP.

 1. (Advanced) Set permissions to their defaults in the registry

Disclaimer: The registry contains system-related information that is critical to your computer and applications. Before modifying the registry, be sure to make a backup copy of it. Adobe doesn't provide support for problems that can arise from improperly modifying the registry. Adobe strongly recommends that you have experience editing system files before you modify the registry. For information on the Windows Registry Editor, see the documentation for Windows or contact Microsoft Technical Support. 

Perform these steps during Acrobat or Adobe Reader installation. The Administrators group is the default local administrative group for Windows.

Windows Vista and Windows 7

  1. Write down the path to the key in the error message and leave the installation running. For example: HKEY_LOCAL_MACHINE\SOFTWARE\Classes\.pdf\PersistentHandler.

  3. Back up your current Registry file:
    1. In the Registry Editor dialog box, choose File > Export

    3. For Export Range, choose All.
    4. Click Save and close Regedit.

If you can't change permissions or rename that key, contact Microsoft or your hardware vendor for assistance.  

2. Remove spyware

Scan for these programs with an anti-spyware utility such as Ad-Aware, available at www.lavasoftusa.com.

3. Check your system for viruses

Use current anti-virus software, such as McAfee VirusScan, to check your system for viruses. Make sure that you have the latest virus definitions for the anti-virus software you use. For instructions, see the documentation for the anti-virus software.

4. Disable Webroot Spy Sweeper

For more information or help disabling Spy Sweeper, contact Webroot Corporation. Adobe technical support does not support third-party applications.

6. Visit the forums

See if other users are experiencing similar problems by visiting the Adobe forums for Acrobat or Reader, or the Deployment & Installation forum on AcrobatUsers.com. If you don't see your issue listed, post it on the forums for interactive troubleshooting. When posting on forums, include your operating system and your product's version number. 

Additional information

Error 1402 occurs when the Windows installer is unable to read a particular registry key. Installation can fail because the Acrobat or Reader installer attempts to clean up registry keys of previous versions of Acrobat or Reader. This cleanup is necessary to avoid conflicts with Acrobat or Reader plug-ins and add-ins for third-party software.

Error 1406 occurs when the installer cannot successfully write a registry key essential for installation.
