Issue Details

  • When I open my standalone application that uses LabVIEW Remote Front Panels I am missing its contents, there is an empty box in the browser where the Front Panel should be.
  • I developed a LabVIEW VI with a Remote Front Panel in LabVIEW (64-bit). I built it into an application (EXE). I am hosting this Remote Front Panel on the development machine. On the client machine, I have LabVIEW RunTime Engine (64-bit, same version as the development system). When I try to connect to the Remote Front Panel using Internet Explorer, the background of the VI is displayed. However, all the controls are missing.

Solution

Missing Remote Front Panel components when using LabVIEW Standalone applications can occur due to different causes, missing the proper LabVIEW Runtime engine, or issues related to Active X or 32-bit processes involved could be causing this unexpected behavior, follow the next recommendation to try to solve this issue:
  • If the VI is displayed using ActiveX controls. There are two ways to use ActiveX to see your Front Panel.
    • Open the link in Internet Explorer. If you see a button at the bottom of the screen prompting you to enable ActiveX, click allow for it to run.
    • Open Google Chrome and find the IE Tab in the Chrome Appstore. Follow the instructions to properly install that extension. Open the link to your Remote Front Panel using the IE Tab extension.
  • Check you are using the appropriate Runtime Engine. The target computer must have the LabVIEW Runtime Engine installed and it must match the version of LabVIEW used to develop the executable.
  • If your application was developed in a LabVIEW 64-bit version, consider Internet Explorer runs as a 64-bit program by default, however, each of the tabs runs as a 32-bit process. Therefore, aside from the 64-bit LabVIEW Runtime Engine, downloading and installing the 32-bit LabVIEW Runtime Engine may also be needed.
