LabVIEW could not find the global VI in the file system when loading this VI. It has been moved, deleted, or its name has changed.
LabVIEW stores global variables in separate VIs called global VIs. If you see this error message, the VI uses a global variable, but LabVIEW cannot find the VI that stores that global variable. The missing global variable is dimmed, as shown in the following illustration.
To correct this error, you can recover the global VI, re-link the global variable to the new location of the global VI, or delete the global variable and create a new global variable. If you create a new global variable, you must update all places where you used that global variable so they refer to the same one.
To re-link to the global VI, right-click the global variable and select Replace from the shortcut menu to display the Functions palette. Click the Select a VI palette icon on the Functions palette and navigate to the file that defines the global variable.
