I have a partion on OSX running Windows 7. I have installed QGC on W7 to to compare the running of the software through different operating systems on the same computer.
However when trying to open QGC after installation I see this message:
I have reinstalled but still get this error message.
ArduSub and QGC are actually only officially supported on Windows 10, OSX, and Linux at this time. Any other Windows version is quite finicky regarding the video streaming, and there are only some certain hardware combinations that appear to work well with QGC on W7.
