I forget to say that download package from qt.io is toooooo slow, average 57KB/S, I have to wait hours!!! So I unchecked the Qt5, I wanted to uncheck the Qt creator, because I have Qt creator installed.The result was that two Qt creators were installed on my computer.When I opened and ran the example project, qt creator showed that can not find VPApplication.h.
Downloads from the Qt servers are unfortunately very slow outside of Europe true, that’s the reason why we provide a custom installer with a pre-bundled Qt version.
Disabling the Felgo repository seems strange as you were referring to the download.qt.io URL which got stuck at 99% in the other thread. When opening the maintenance tool and adding the Felgo URL back, does the installation then work? I guess you had no chance to copy us some log output as stated above?
