I don't think I have to repair the installation. It is LabVIEW 8.6 not 8.6.1. I think I understand what I did to cause the problem. It's something that reflects some of my mindset when I program. I do some up front design and planning, but when I start to program, other things come out and I make changes on the fly as I go.
The sequence of events is this...
1. Create a class
2. Added 4 booleans
3. Created some dynamic vi's by right clicking on the class in the project window. Save the newly created VIs.
4. Delete the booleans from the class definition and add some numbers and strings instead.
5. Do not delete the original dynamic vi's
6. Close LabVIEW and go home.
7. Next morning re-launch the project file and when LabVIEW tries to link the vi's to the class it doesn't know
what to do. So it asks if I want to add, remove or cancel re-linking the original vi's. If you tell it to relink or even cancel, LabVIEW dies.
8. The message: "DAbort: Should never have already existing class when patching the thing that is loading the class!" appears.
Perhaps you should just add a check for an insane object between the CRT and the chair!
Thanks. While I don't like getting crashes, this one I think is understandable.
