Issue Details

While opening any LabVIEW VI, an error window shows up saying:
There was a problem sending the command to the program.

The VI still opens and works but the window is showing up everytime. What I can do to fix this?


This error can be caused by many different reasons, and can be an inconvenience but it doesn't limit LabVIEW's functionality.

To temporarily avoid this error:
  • Open LabVIEW, then click on File>>Open>>[Your VI] 
  • Right click the VI and choose Open with>>LabVIEW.
To permanently correct this behavior you could:
  • Add local Administrator privileges to your user account.
  • Set the default program for .lvproj and .vi files to notepad.exe. Then set it back to LabVIEW.
  • Disable Run this program as an administrator by right clicking the LabVIEW shortcut and going to Properties>>Compatibility.
  • Update your Windows OS to the latest available version.
