Issue Details

I am getting a message that my license is expired, corrupt, lost, or activated for a different computer. I have tried to enter my serial number, but according to LabVIEW the resulting activation code cannot be applied. How can I reactivate LabVIEW?

Solution

If your license files have expired, been corrupted, or lost, you will need to replace them with the default Evaluation License Files for your software. These are the license files that install with your software before the software is activated, and you can search for and download the Evaluation License Files that match your version of software at ni.com/downloads.
  1. Find and download the Evaluation License Files that match your version of software at ni.com/downloads.
  2. Use these downloaded files as replacements for the expired, corrupted, or missing license files by replacing the corrupted files with the new license files.
  3. After you insert these license files to the Licenses folder, verify that your software is operating in evaluation mode.
  4. Now, you can fully reactivate the software in the NI License Manager by right-clicking on the name of software in the tree and selecting Activate. Then, follow the prompts to activate LabVIEW using your licensed serial number.
