Hello all!


i know someone have encountered the problem:  "generic error, Labview load error code 3: Could not load front panel"


in labview 2011 before, but there is no solution  in detail. it would cost me much time to rewrite the vi.

So im very gratefull if  anyone could help me with it.

Prime example of why everything should be in a source code control.  Because then you could just check out the last version that still worked.

Hi Panliang,


as crossrulz said: get the VI from your backup.

If you don't have any backup: start to create backups from now on.

Or setup some kind of source code control like SVN or GIT…


On your VI: it's big. It's bigger (in term of file size) than 99% of all VIs I ever have seen before.

The bigger the file the more errors can occur. And it crashed my LV2016 after trying to open it…


When you recreate your VI: limit the size to reasonable amounts. This applies to BD/FP size (in pixels) as file size in bytes too!

Best regards,

I do not know why your vi is so large, but be careful not to save large amounts of data into the vi by loading data into huge array controls and then using "Make Current Values Default".
