Issue Details

I have a VI that could be opened previously in the LabVIEW development environment. Now when I try to open the VI, I get the following error: LabVIEW load error code 3. Could not load front panel.Why am I getting this error and what can I do to get my VI working again?


Two different issues have been resolved in Service Pack 1 (SP1) of LabVIEW 2009. If you are using LabVIEW 2009 these issues were resolved in the LabVIEW 2009 f3 patch. Please install this patch if you are using LabVIEW 2009, or upgrade to LabVIEW 2009 SP1.   

If upgrading to SP1 or installing the patch described above does not resolve this error, please check whether the issue is related to any of the issues described in the articles in the related links section below.

Additional Information

Error code 3 is a generic error that is displayed when LabVIEW cannot load the front panel of a VI. This can be caused by a corrupt front panel object.
