LabVIEW 2025 Q3 Does Not Include a Dedicated Report Generation Toolkit Version and Displays Missing or Unlinked RGT APIs and Examples

Issue Details

In LabVIEW 2025 Q3, there is no dedicated Report Generation Toolkit (RGT) 2025 Q3 release, which is expected behavior. National Instruments does not publish toolkit versions for every LabVIEW release; instead, a single toolkit version may support multiple LabVIEW versions before or after a given release.

When using Report Generation Toolkit for Microsoft Office 2026, I observe:

Examples not appearing correctly in the LabVIEW Example Finder, even though they exist on disk at:

• C:\Program Files\NI\LVAddons\rgt\1\examples\Report Generation\Excel Reports\

Some RGT APIs not visible in the LabVIEW palettes, although the VIs are present at:

• C:\Program Files\NI\LVAddons\rgt\1\vi.lib\addons\_office

Solution

1. Copy the Excel Folder into the LabVIEW 2026 Installation

Locate the Excel folder from the Report Generation Toolkit add-on directory:

• C:\Program Files\NI\LVAddons\rgt\1\vi.lib\Utility\NIReport.llb\Excel

Copy the entire Excel folder to the LabVIEW 2026 vi.lib directory:

• C:\Program Files\National Instruments\LabVIEW 2026\vi.lib\Utility\NIReport.llb

Note: This ensures that LabVIEW 2026 can correctly locate the Excel-related Report Generation VIs and classes at run time.

2. In your LabVIEW project, add the following class manually:

• C:\Program Files\National Instruments\LabVIEW 2026\vi.lib\Utility\NIReport.llb\Excel\NI_Excel.lvclass

Save the project after adding the class.

3. Include the Excel Class in the EXE Build Specification

Open the Build Specifications for your EXE.

Navigate to Source Files.

Move NI_Excel.lvclass to Always Included.

Note: This step ensures that the Excel Report Generation classes are deployed with the executable.

4. Modify the Report Generation Toolkit Add-on Configuration

Open the following file in a text editor with administrator privileges:

• C:\Program Files\NI\LVAddons\rgt\1\lvaddoninfo.json

Locate the following content:

{

 "AddonName": "rgt",

 "ApiVersion": "v1",

 "MinimumSupportedLVVersion": "26.0"

}

Change the MinimumSupportedLVVersion value from 26.0 to 24.0:

{

 "AddonName": "rgt",

 "ApiVersion": "v1",

 "MinimumSupportedLVVersion": "24.0"

}

Save the file.
