fatal error: LABVIEW.LIB was not called from a labview process

[mstudio]

I have built a very simple executable which uses shared variables which should talk to an OPC server. When I try to run it on the target machine, I get this error. Does anyone know what it means?

Thanks for the link, very helpful. I did indeed convert my project to version 8.2 from version 8.5, from reading the article it sounds as though all I need to do is a mass compile, and then all should be well?

[rsw]

If you up/down graded from 8.2 to 8.5 then I would suggest doing a mass compile on the VI's into a new folder (or have a backup of your files somewhere).

You can do this via LabVIEW > Tools > Advanced > Mass Compile.

Please let me know how this turns out.

All the best,

I did the mass compile, and now its seems to be working fine, so thanks for the tip! I also unchecked the "enable enhanced dsc run-time support" option on someone else's advice, so I'm not sure whether it was that that helped, or maybe both things were required.
