To remove the serial number and user information from the splash screen that appears when LabVIEW launches, a token must be added to the LabVIEW.ini file.
This file is located in the directory in which you installed LabVIEW. By default, on a Windows 7 machine, that path will be:
<Program Files>\National Instruments\<LabVIEW>
Once you locate the file on disk, right-click the file and select
Edit. Then add the token:
UseMarketingSplash="True"
Save the LabVIEW.ini file to apply the changes. Now when you launch LabVIEW, the splash screen will appear without the serial number and user information.
