--- Comment #1 from Zebediah Figura <z.figura12 at gmail.com> ---
Something is broken with the software. A +module trace yields:

0009:warn:module:import_dll No implementation for
Qt5Gui.dll._ZN14QImageIOPluginC2EP7QObject imported from L"C:\\Program
Files\\RigExpert AntScope2\\imageformats\\qjp2.dll", setting to 0xf40276

qjp2.dll and some others seem to be trying to import symbols using a different
C++ name mangling scheme than Qt5Gui.dll and others are using to export
symbols. For example, the one in question should be:

      237     0x697f0    ??0QImageIOPlugin@@QAE at PAVQObject@@@Z

The Qt5 DLLs seem to have been incorrectly built or distributed.

I guess it works on Windows since the offending DLLs are imported with
LoadLibrary() rather than linked directly, in which case I believe that
LoadLibrary() simply fails. I'm not sure, though. In any case
WINEDLLOVERRIDES="qjp2=d;qmng.dll=d" is sufficient to let the application
launch for me.
