LabVIEW load error code 3: Could not load front panel

[wmpimenta]

• What line did you add to the INI and why?

There is a kind of solution in for this error. This is the procedure...

                Instructions to fix a corrupted VI in 2011 or higher:

               1. Close LabVIEW

               2. Add connPaneRecoveryMode=True to the LabVIEW.ini file (-The LabVIEW.ini file is located in the                  National Instruments folder>>LabVIEW 2011>>LabVIEW.ini)

              3. Open the corrupt VI.

              4. Push Ctrl+A on the block diagram and the copy and paste to a new VI.

             5. Save the new VI.

             6. Close LabVIEW and remove the ini token (VERY IMPORTANT)

            7. Restart LabVIEW and load the new VI and verify it is correct. Save

I tried but it did work.

• Why is the VI so big?

This vi is used to control a camera, a photo-diode (detector), that it is used to see a cloud of atoms in our lab. From this two devices, the vi process the images and the data with other programs.

• Are you sure the VI was not saved without front panel?

I tried to open the same vi I use to open with labview 7.1 in labview 12.

• Any particular reason you are using 64bit LabVIEW?

It is the one we have avaliable in the lab.

Best Regards.

Hi wmpimenta,

I tried but it did work.

So when this version of the VI doesn't load you have those options:

- try to load it in LV7.1 and check for sanity with the LabVIEW version the VI was created with

- try to get the same version of the VI from a second backup, mnaybe it's a simple file system corruption problem

- get an older version of the VI from your source control repository until you can open the VI again!

When you can't follow these 3 options: recreate the VI from scratch - and setup some source control system before you start coding!

Why is the VI so big?

Apart from your description: it is also big because it references several ExpressVIs - they tend to bloat up VIs… 🙂

Hi Edwin,

no, the same problem here.

Get an older version of this VI from your backup or SCC tool.

Hi,

I have a same problem. If I want open .vi there is an error: "LabVIEW load error code 3: Could not load front panel".

I'm using LabVIEW 2016. I tried add connPaneRecoveryMode=True to .ini , but it is not working to me.

Could somebody help me and recover attached VI, please?

Hi Udrzba,

LabVIEW2017 could open your VI!

It is missing a lot of subVIs/typedefs as well as some WireChannel settings…

(Why don't you get a copy from your backup?)

Hi GerdW,

Thank you very much!

You saved my life 🙂

Ironically, that is "Not the Solution" 😮

Hi

I'm using Labview 2017 .It was working fine until one of my vi's started showing up this generic error :Can't load front panel and I don't understand why.

I tried the standard instruction you had offered earlier.It didn't work for me.

I'll attach the vi in this thread.Can you help me undo this error?

Thanks in advance

Hi Denesh,

I tried the standard instruction you had offered earlier.It didn't work for me.

So you tried to get an older version of that VI from your backup or (much better) SCC system?

Why didn't work that for you?

Btw. I get the same error with your VI. Solution: get an older backup of that VI!
