I am having trouble building an executable from a fairly large application in LabVIEW 2012. The application runs fine in the development environment. The project uses about 50 classes and several hundred sub-VIs. I had some initial problems with build error 1502 (cannot save a bad VI without its block diagram), but after enabling debugging I am able to successfully build the EXE. However, when I run it, a small dialog pops up before any front panels are opened: LabVIEW: Generic File I/O Error. The file "Hardware Detector.lvclass" could not be loaded. After hitting OK, my splash screen opens up with a broken arrow, and another dialog reads VI has an error of type E208. The full development version of LabVIEW is required to fix the errors. This is one of the classes used in the project. Based on advice I've seen other posts, I've tried a few things: Unchecking all boxes under Additional Exclusions (don't disconnect typedefs, don't remove extra files, don't disconnect inline subvis, ...) Adding the class folder to the Always Included list under source files (actually its grandparent folder) None of these seemed to make a difference. The only things I can think of that are unique about this class are that 1) it resides under a fairly deep folder hierarchy (five folders below root) and it makes use of the Set/Unset Busy Cursor VIs. I don't know if any of that matters. Any ideas?
