Issue Details

I'm trying to view detailed help in LabVIEW, but the right browser in detailed help is completely blank. The left side shows a list of items and the context help works fine. How should I fix this?


It is possible that LabVIEW has corrupted files. 

1) Check if the lvhelp.chm file is located in the LabVIEW folder. An example path this file is located in is C:\Program Files (x86)\National Instruments\LabVIEW 2017\help
  • lvhelp.chm a complied HTML file that LabVIEW help uses
2) Repair LabVIEW 2017 using this documentation: Uninstall or Repair National Instruments Software or Drivers in Windows
