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 V-Play 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 V-Play URL back, does the installation then work? I guess you had no chance to copy us some log output as stated above?
Thanks a lot,
