Exception occurred: node 0x0 of subVI "NI_AALPro.lvlib:General Polynomial Fit"

[timpersoons]

I've recently been receiving this error message when using the General Polynomial Fit:

------
An exception occurred winthin the external code called by a Call Library Function Node. This might have corrupted LabVIEW's memory. Save any work to a new location and restart LabVIEW.
VI "myVI.vi" was stopped at node 0x0 of subVI "NI_AALPro.lvlib:General Polynomial Fit.vi"
------

I've reinstalled LabVIEW entirely, making sure to delete all remaining files after uninstall. I've tried to update LV 8.0 to 8.0.1, with no success. I'm using LabVIEW 8.0.1 on WinXP SP2.

Any ideas would be very welcome.

Thanks

Can you post your code?

This is the code.

In sequence 1, it performs a polynomial fit to 12 [X,Y] points, then in sequence 2, it uses the coefficients to interpolate.

It has always worked before; the error suddenly showed up a few days ago. The error remains after reinstalling LabVIEW and upgrading from 8.0 to 8.0.1.

It sounds like something either got messed up in the upgrade process, or there's something in V8.0.1 that is wrong. Do you get the same error when running one of NI's examples using these fitting VIs? What happens of you go back to V8.0?

The same error occurs when using LV's "Regressions Demo.vi". Linear and Exponential fit give no problems, only the Polynomial Fit.

The error was already occurring in LV 8.0. That's the reason I tried upgrading to 8.0.1.

Hi

Have you tried a repair on your LabVIEW installation, it sounds as if some part of the installation has become corrupt. Try a repair, if this does not resolve the issue post back on this thread and I will suggest how to complete a complete uninstall that will enable a fresh install of LabVIEW.

I've already tried a repair. When that didn't solve the problem, I've uninstalled LV and all other NI products, deleted the remaining Program Files\National Instruments directory, but the problem still persisted.

Hi

When you uninstall LabVIEW and NI Software there are sometimes still references left behind. The following utility known as MSIBlast will completely remove NI software leaving you an environment to carry out a fresh installation of NI software.

The utility and instructions on use are in the ZIP file below. I highly recommend that you follow the instructions as close as possible.

Let me know how you get on.

Kindest Regards

I've just used the removal utility, following all given instructions. Have just reinstalled LabVIEW, and tried the "Regressions Demo.vi" in the example finder. The same error keeps popping up when attempting to use the Polynomial Fit (see attached screen capture).

Thank you all for your help; I guess I'll have to try and find another way of implementing my VI, without the Polynomial Fit.

Hi

Have you tried installing LabVIEW and the relevant drivers onto a clean machine that has not got LabVIEW installed and see whether you still experience the issue?
