Odd error starting happening...

[shew82]

All of a sudden I'm getting an error every time I edit a VI's icon (LV 2013):

Clicking OK to that and several similar errors (all "Could not load front panel") eventually leads to the icon editor properly opening but dismissing 5 error messages every time I edit an icon is going to get old real quick...

Any ideas on what could be causing this (I havent changed the icon editor packed library)?

Have you done any updates (e.g. SP1 or f1 patch) or installed anything recently? That is an odd error, because most of the front panels in a packed library are gone by design.

Nope - it just all of a sudden started happening this morning. Closing LabVIEW didnt seem to help. :S

If you haven't modified the Icon Editor, then my only ideas are to (1) repair your LabVIEW installation (in case any of the source files somehow got corrupted), or (2) rename your LabVIEW.ini file to LabVIEW.bak and restart LabVIEW to see if there are any errant entries in your INI file that would cause problems.

It's come back today.

Looking through my Windows logs it looks like our IT was pushing out some GPOs yesterday, installing some software etc. I wonder if that temporarily messed up LabVIEW.

Hi!

I have exactly the same problem.

Since I have to PCs running with the most recent LV2013 SP1 (the other is working fine), I could track down some issue when opening the "lv_icon.lvlibp" in the Labview 2013\resource\plugins foldery. On the system that works, I could open the lvlibp without errors. On the other PC I get some errors:

"Error loading "DOMUserDefRef.dll". Device is not ready. AND

"LabVIEW: Resource not found.  An error occurred loading VI 'lv_icon.lvlibp:NI_XML.lvlib:Close Reference(Node).vi'. LabVIEW load error code 3: Could not load front panel."

This DLL can be found in the Labview 2013\resource folder.

And here I am stuck again. Solutions or some further ideas are welcome....

Best Regards

Martin

Have you tried a repair of the LabVIEW installation?

[mawodorfer]

This error occures at my newly installed LV2013 development suite.

I also startet the repair. Did not change anything... ;-(

I just checked on a system running LabVIEW 2013 SP1 and did not have any issues. Let's check the file size and mod dates of your icon editor .lvlibp, and that DOM DLL...here's what they are on my system (Windows 7 32-bit, running LabVIEW 2013 SP1 32-bit...please tell me if you're running something different):

resource\plugins\lv_icon.lvlibp:

resource\DOMUserDefRef.dll (including "Details" page for version info as well):

Since, I am using a german windows, the dialogs are in german. But I think, the needed information is readable 😉

I have an idea that it has something to do with certificates, because I have a similar problem when loading the NI OPC Server DLLs. (DLLs could not be loaded due to a "certification validation failure")

Does anybody know how NI handles or uses certificates?
