Issue Details

I am using Report Generation Toolkit. My application works in the development environment, but when I try to run the executable (EXE), I am getting the following error:

Error 7
LabVIEW attempted to load the class at this path:
…… vi.lib\Utility\NIReport.llb\Excel\NI_Excel.lvclass


Manually add the NI_Excel.lvclass to project and add to the Always Include folder in Build Options.
