Issue Details

  • My computer has LabVIEW installed and was activated with a serial number. I can no longer boot up my computer and I wish to retrieve the LabVIEW license or the serial number in order to use it on another computer. 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?
  • I misplaced the physical media for the LabVIEW installed on my computer. The computer I was using no longer works and I would like to continue using LabVIEW on another computer. However, I cannot locate the serial number. 


You can retrieve the LabVIEW serial number from where it is stored inside the LabVIEW ADE configuration .ini file.
  1. Find the LabVIEW ADE configuration .ini file, located in the path specified for your operating system:
    • 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 the ProgramData folder, you will need to enable the "Show hidden files" option. Navigate to Start >> Control Panel >> Folder Options >> Views >> Files and Folders >> Hidden files and folders, select the Show hidden files, folders and drives option.
  2. Open the .ini file using a text editor. You will find the Serial Number under "SerialNo" key, "LicenseInfo" section, as long as 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.
