Error - NI SystemLink™ Message Broker Installation Has Failed When Installing LabVIEW Built Installer

Issue Details

I have a web service application developed and built with LabVIEW™ 2021 SP1 (64-bit). It has already been deployed to several machines and confirmed to be working correctly.

We ported this application to LabVIEW 2024 Q3 (64-bit) and rebuilt it. When installing this application on the deployment machine, the following message appears during installation:

The "NI SystemLink Message Broker" installation has failed.

Continue?

If I choose to continue, the installation itself completes, but the application does not function correctly.

The additional installers added during the build are the same as in 2021 SP1:

• NI System Web Server 2024 Q3
• NI System Web Server Deployment Support for LabVIEW 2024 64-bit

Solution

This issue occurs when installing a LabVIEW‑built installer that includes NI Web Server components.

Follow the steps below based on your application requirements:

1. If your application is not using any web service or SystemLink API, you can uncheck the below items from the Additional Installers list in the Installer Build Specification.
   1. NI System Web Server
   2. NI Web Server Deployment for LabVIEW
   3. NI LabVIEW Web Server
2. If you need NI Web Server in your application, you can distribute it as a package instead of installer.
3. If the issue persists, it may be caused by NI software not being fully uninstalled. Force the uninstallation of NI software by running the following command, as described in Automating Uninstallation of NI Software:  uninst.exe /qb /x all
4. If the issue is still not resolved, collect the installation logs as described in Creating an Error Log File for a Software Installation and contact NI Support.
