Symptoms

When trying to activate FineReader PDF for Mac with an SLE license manually with a serial number, the error message appears:

Invalid serial number. The serial number you entered is invalid. Please provide a valid serial number to activate ABBYY FineReader PDF.

Cause

The incorrect distributive was used for installation. The SLE distributive does not require activation. The license file is included in the distributive, which is provided to each customer separately.
