Software

  • LabVIEW

Issue Details

Everytime LabVIEW is opened (any 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?

Solution

This error can be caused by many different reasons, nevertheless this should be an inconvenience and shouldn't limit LabVIEW's functionality.

To temporary avoid this error:
  • Open LabVIEW. Then open your VI from LabVIEW.
  • 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" check. Right click LabVIEW shortcut, go to Properties>>"Compatibility" tab.
