    Their download speeds are a joke.
    And they expect people to pay for it? It's been 2 hours already and I'm not even on 10%

    I was looking for an alternative to tkinter, but now I get what "simple" meant on tkninter's description.

    Just pass on this, the forums don't allow you to store pictures? what a joke. It's 2023 people.

    This sounds like you're interested in just the python bindings. Then actually

    pip install pyside6
    

    is your friend :)

      @JonB said in Slow download speed:

      if you pay for a commercial license is there not a faster download available to you?

      Yes. Commercial customers are served via Amazon AWS. For open source users, we're relying on a network of servers: https://download.qt.io/static/mirrorlist/. Typically the speed are OK there, but it happens that some servers just get slow, and then the list need to be tweaked ...

      So I don't know why @Jorge-Escobar is complaining about "And they expect people to pay for it?", if he is paying for a commercial licence he should use that.

        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!

          @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
