Issue Details

My computer has installed LabVIEW and it was activated with a serial number. I have problem to boot up my computer and I wish to retrieve the LabVIEW license or the serial number for my other computer usage. How can I retrieve the serial number if I can still read files and contents inside the hard disk via a hard drive reader or adapter using Windows Explorer?


You can retrieve LabVIEW serial number that is stored inside LabVIEW ADE configuration .ini file.
The file is located in
  • Windows XP: <Documents and Settings>\All Users\Application Data\National Instruments\LVProductDLLInfo\<version>\LabVIEW_ADE_<version>
  • Windows Vista/7/10: <ProgramData>\National Instruments\LVProductDLLInfo\<version>\LabVIEW_ADE_<version>
To access ProgramData, you will need to enable "Show hidden files" option. Go to Start >> Control Panel >> Folder Options >> Views >> Files and Folders >> Hidden files and folders, tick on Show hidden files, folders and drives option. 

Open the .ini file using a text editor. You will find the Serial Number under "SerialNo" key, "LicenseInfo" section, if you have previously activated your LabVIEW using the serial number.

Additional Information

The suggested way of retrieving serial number of LabVIEW is only applicable to LabVIEW. You will not able to retrieve the serial number of other NI software, e.g. TestStand, in the similar way.
Per NI Software Policies and NI General Purpose Software License Agreement, for Single-Seat user, you are allowed to retrieve the serial number and use it to activate LabVIEW on another computer.
