3.1.What bit version are you running? The best way to check what bit version you are running is to go into the following directory of each version you want to check;

C:\Niagara\Niagara-xxx\bin

Double click console.exe and type the following;

nre -version

The console will then populate with the following text;

32bit




64bit

4. All my bit version match, now what?

If you find that you are running the same bit versions, but the Host IDs are still different, can you do the following.

It is a known issue that Microsoft Windows© updates could change the Niagara Host ID. Tridium introduced a fix for this issue in our most recent supported releases of Niagara. These builds are• Niagara 3.8 Update 2 (3.8.213 and later) • Niagara 4.3 (and later) • Enterprise Security 2.3 Update 1 (2.3.118 and later which is based on Niagara 3.8.213) Updating older versions of Niagara

Tridium always recommends that Niagara installations are upgraded to the latest released software in order to maintain the latest security protection and to gain benefit from latest features. Tridium has created patch files to stabilize the Host ID for cases where customers have not upgraded to the latest version of Niagara (see installation instructions below). Once these patches are applied to the older versions of Workbench the Host ID is stabilized and should not change if Windows updates are installed.

IMPORTANT NOTES REGARDING THE PATCHES - Patches are only supported for the latest update version for the relevant release. 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 considered unsupported. Customers applying these patches do so at their own risk. Newer versions of Niagara (3.8U2 and 4.3) have introduced a stabilized method of managing the Host ID and do not require any patch. The patches do not eliminate the issue of different Host IDs generated when installing 32 bit and 64 bit

• Download and unzip the file from the link below HOSTID_PATCHES.zip into a temporary folder.

• The archive contains 'nre.dll' for various versions of Niagara AX and Niagara 4.2 in a directory structure identifying them first by Niagara version and sub-directory identifying 64-bit or 32-bit Windows. The 4.2 folder also contains 'njre.dll' which will need to be copied only for 4.2 installations.
• Stop any running station using Workbench's Platform Application Director on the platform to be. patched.
• Exit Workbench if running on the platform to be patched From the Niagara Command Line (/bin/console.exe execute the command: plat uninstalldaemon.
• Make a copy of the existing nre.dll located in /bin folder. If Niagara 4.2 is being updated also make a copy. of njre.dll located in /bin folder.
• Copy the version appropriate and OS appropriate (64 or 32 bit) downloaded version of nre.dll file to the. /bin folder. If Niagara 4.2 also copy njre.dll to /bin folder. Overwrite the existing file(s).
• From the Niagara Command Line (/bin/console.exe) type: plat installdaemon.
• Start Workbench. Open a platform connection to the patched platform. Using the Application Director, start the station.
