Issue

When you try to launch Adobe Acrobat 8 Standard on a Dell computer, the program returns the error message, "You have entered an invalid serial number. Please re-install Adobe Acrobat 8 Standard and enter a valid serial number when asked."

To the top

Solution

Check the alm_config_files folder for a duplicate AdobeConfig.xml file.

  1. Navigate to the following folder:

    C:\Program Files\Adobe\Acrobat 8.0\Acrobat\alm_config_files
  2. The following two files should appear in this folder:

    • AdobeConfig.xml
    • AdobeConfig.xml.aiwbf
  3. Delete the AdobeConfig.xml file.
  4. Rename the AdobeConfig.xml.aiwbf to AdobeConfig.xml by deleting the "aiwbf" suffix.
  5. Launch Acrobat 8 Standard.
To the top

Additional Information

On some Dell computers, a duplicate AdobeConfig.xml file is created when Acrobat 8 Standard is installed. The AdobeConfig.xml file without the "aiwbf" suffix is written for a volume-license version. The correct AdobeConfig.xml file is given the suffix. When a retail version of Acrobat tries to read the volume-license AdobeConfig.xml file, Acrobat returns the error.
