Slow download speed
-
Good evening to all.
I tried to install it myself and it was taking days. Now just a few minutes!I created a shortcut of the executable file by adding a parameter. I chose a mirror from Europe.
...\qt-unified-windows-x64-4.6.0-online.exe --mirror https://qt-mirror.dannhauer.de/
Select mirrors from here: https://download.qt.io/static/mirrorlist/@CostasBal
Also works on macOS, in which case pull out .app and from the terminal:
./qt-unified-macOS-x64-4.6.0-online.app/Contents/MacOS/qt-unified-macOS-x64-4.6.0-online --mirror https://qt-mirror.dannhauer.de/Finish installation in minutes! Great job!

Select mirrors from here: https://download.qt.io/static/mirrorlist/@CostasBal Currently also experiencing horrible download speeds
But nowadays we can just use the Qt installer with an option to select the mirror. On Windows it is .\MaintenanceTool.exe --mirror https://somemirror.com (with one address from https://download.qt.io/static/mirrorlist/)
No need to use the old Repo Chooser anymore

Correct.
You cannot use the old Qt SDK Repo Chooser anymore as it does not work with the latest installer. Fortunately, Qt SDK Repo Chooser is no longer needed because the latest installer lets you select a mirror via a console argument.

@csab6597 Googling that error I found https://forum.qt.io/topic/146776/qt-online-installer-file-not-found from 5 days ago. For me also Installer version 4.6.0 didn't work, so I tried version 4.5.1 and it worked (found it from my downloads folder, I don't know how to get older versions from the website)

Fast forward 2025, it's the same - below 100KB woke speed. The joker who mocked the guy who asked this genuine question taunting on his/her internet speed read here - my browser is downloading data from other sources at 90 - 120 Mbps effective speed and this sucker installation isn't going over 100Kb. Assuming that joker was getting good download speed at installation, means either they are releasing full bandwidth only for some privileged geographies OR they have extremely poor infrastructure even after 7 years.

@Bhagwate Try another mirror, see https://wiki.qt.io/Online_Installer_4.x

I just found a workaround. You can download the offline installer using Google Colab. It downloads incredibly fast. Then you can copy the offline installer to your google drive and download from there. From here it depends on your internet speed
