This error might be occurring because the LabVIEW Data folder is pointing to a network server or a location that the computer does not have access to when trying to edit or create an icon.
To fix this error follow these steps:
- Open LabVIEW and go to Tools >> Options... >> Paths.
- Click on the dropdown list and click on Default Data Directory*, unselect the Use default checkbox and select a new path by clicking on Browse...
- Once you are able to change the path for the new local folder, click on Replace and then OK.
- Close LabVIEW and reopen it, now you should be able to use the LabVIEW Icon Editor.
