Add LDF file to Vectorworks

If you are seeing a dialog with the error message "License validation failed" upon first starting Vectorworks, it means there is still a file missing from the Vectorworks user directory that reads your serial number, called the LDF file.

You can add this file by following the steps below:

• Log in to the Vectorworks Customer Portal or Student Portal .
• Go to the tab ‘Licenses’
• Click on the download icon next to the serial number, the .ldf file will be downloaded.
• Open Vectorworks and the error dialog will reappear.
• Click on 'Provide LDF…'.

• Browse to the desired .- file, and click ‘Open’.
