Issue Details

I recently installed the Real Time module for LabVIEW. When I open a VI hosted on a Real-Time target, LabVIEW crashes and I have to reopen it. I can open VIs hosted on my PC or an FPGA target without any issues. I have even reinstalled my software, but the issue persists.

Why are only the RT VIs causing LabVIEW to crash?


To Fix this issue you need to perform a force reinstall of the Real-Time module.
  • Go to the download page for the Real-Time module and download the installer according to your LabVIEW version.¬†Even If you have an installer at hand it is highly recommendable that you download a new copy from Just in case the installer is corrupt.
  • Follow the steps on this article to perform a force reinstall¬†with the installer you just downloaded.
