During an application build, I got "Error 7 occurred at c:\Program Files\National Instruments\LabVIEW 6\vi.lib\Analysis\8numerc.llb\1D Linear Evaluation.vi - source does not exist". This existed in Labview 5.1.1. Was it deleted in 6.0?
No, this VI is in the following location "Functions >> Analyze >> Mathematics >> Array Operations>>1D Linear Evaluation.vi"
Perhapse this in a package (Advanced Analysis) that is not included in your version of LabVIEW. You may need to upgrade to get these VIs, or you can copy them over from your Labview 5.1.1 installation.
