How to find out what license is used on a particular workstation?
To determine which serial number is used on a particular computer, please check the license file <serial number>.ABBYY.License. The part of the file name before *.ABBYY.License is the serial number of the product activated on the computer.
The license file is located in the folder: C:\ProgramData\ABBYY\FineReader\<version number>\Licenses.
Please note, the ProgramData folder may be hidden.
Otherwise, please submit a request and specify the Support ID from the computer. In FineReader PDF 15 go to the Help menu > About > License Info > the Support ID combination consists of 24 digits. With the help of the Support ID the information about the serial number can be restored.
