CCI is excited to announce that Tridium has released a new set of patches that no longer requires a license change! 

Over the past year, many of you have experienced the frustration of Windows 10 updates changing the Host-ID of your Niagara Supervisors and Workbench PCs. In some cases, when running multiple versions of Niagara on the same PC, Windows 10 updates would cause 2 different Host-IDs to be generated depending on which version of Niagara was running. The traditional method of dealing with this was to call CCI and have your computer’s license replaced; however, now all you have to do is apply the new set of patches! 

Please refer to CCI’s Google Drive Site to find a download link and instructions on how to apply software patches for Niagara 4.2 and Niagara AX versions 3.6, 3.7 and 3.8. Here is the direct link:


  • Your machine should be actively licensed for whatever Host-ID is generated by Niagara 4.3 and 4.4 (and higher) or Niagara AX 3.8.213 (and higher).
  • Niagara 4.3, 4.4 (and higher) and Niagara AX 3.8.213 (and higher) do not require patching. These specific versions of Niagara, as well as all future releases of Niagara, have the patches built in.
  • Patches should be installed for the latest updated version of Ax 3.6.407, 3.7.108, 3.8.111, and N4.2.36.38
  • Patches are not available for AX 3.5 and earlier, or Niagara 4.0 or 4.1.
  • Builds prior to AX 3.8.213 are technically considered unsupported by Tridium. Customers applying these patches do so at their own risk.

After applying the software patches, multiple Niagara versions on a single machine can be maintained using a single Host-ID. Further, these patches will prevent future Host-ID changes caused by subsequent Windows 10 updates!
