Hi Forestrock,
Thanks for posting to the discussion forums. There are a couple of things you can try to get rid of this error. You can try saving and renaming all the VI's that are called by test.vi and test.vi into a new location. A second thing you can do is physically delete the Nonlinear Curve Fit.vi and replace it. If neither of these options work you may have to reinstall your LabVIEW. I ran your program and it ran error free on my computer. I hope this helps out. Have a good day!

Hi Gavin
What VI are you opening that provides you with this error? In your case what liberary did you replace?

Hi Gavin
Where is this ellispe.vi found? I did not find this VI when searching our functions pallets or in the example finder?

On my machine
C:\Program Files\National Instruments\LabVIEW 8.0\examples\math\curvefit.llb\Fit ellipse.vi

Hi Gavin
I took a look into this VI and did not see any references of it calling the NI_APPLPro.lvlib. What operating system are you using? Open the ellipse VI and try running it in highlight execution, when doing this which sub VI throws the error?

we are using windows XP.
As I said, the error message says that the faulting vi is "Real SVD decomposition.vi". This shows up in the hierarchy for "fit ellipse.vi" (and is listed there as belonging to NI_APPLPro.lvlib. It may be that it is the polymorphic state of "Nonlinear curve fit.vi" that matters? It is set to Lev-Mar.
If I do search for the string "NI_APPLPro.lvlib" on (fit ellipse.vi) and its sub-vis to search for that library, I don't see it either, but if I search using objects and select "VI by name" there are four VIs showing related to this library (three SVD and three matrix).
If I run in highlight execution the failure is in "Nonlinear curve fit".
If I progressively tunnel down in each faulting vi then the thread is:
"Nonlinear curve fit LM.vi" -> "LM get new coefficients.vi" -> "Matrix left divisionMV.vi" -> "Real SVD decomposition.vi" where it appears to fault during the call to "C:\Program Files\National Instruments\LabVIEW 8.0\resource\lvanlys.dll", specifically the function SVDEx_head. I attach a screen shot of the "configuration" for this library function.
Is it possible that lvanlys.dll is corrupt?
