Blank Error Message When Building a Volume License Installer

Issue Details

When I build my volume license installer (VLI) in Volume License Manager, I receive an empty or blank error message with no description.



This issue can be caused by building a Volume License Installer that uses a later version of NI Package Manager than your current installation of Volume License Manager. This has been corrected in NI VLM 3.2.1 and 3.2.2 Patches and documented in Bug 743697 and Bug 937862.

To ensure compatibility, please upgrade Volume License Manager to the latest version. Refer to Upgrade NI Volume License Manager 3.x for more information.

Additional Information

From LabVIEW 2019 and later, all NI installers are now based around NI Package Manager packages. You must have Volume License Manager 3.2 or later to make a custom VLM installer for any software versions 19.0 or later.
