Why does Qt offline installer require internet?

[Q139]

Why does latest and greatest Qt offline installer require internet and are almost all download mirrors broken for weeks?

https://download.qt.io/official_releases/qt/5.12/5.12.11/qt-opensource-windows-x86-5.12.11.exe.mirrorlist

In my case 1 mirror out of 17 worked for download, also tested last week.

@Q139 Qt 5.12.11 is not latest. What exact installer did you download and what does not work if there is no Internet connection?

Qt 5.12.11 is not latest.

Unfortunately, that is the latest offline installer available to non-commercial users. All newer installers are online only.

@JKSH Ah, you're right, forgot about that.

If you have an active network connection, the installer will try to use it to query your account licenses.

To make it truly offline, temporarily disable your network adapters (see https://wiki.qt.io/Ifw_FAQ )

[Q139]

@JKSH Tryed but cannot continue to install with no adapters and various proxy settings.

@Q139 You are out of luck. The QtCompay or whatever, are aggressively pushing to sell the commercial licenses, and that is one of the many nasty moves in the past few years. You are basically either on your own trying to build Qt using their custom qmake system with so may dependencies (like OpennSSL, ICU) but also Python, Perl etc. See: https://doc.qt.io/qt-5/windows-requirements.html
Or option 2, you are stuck with version 5.12 forever. So far the company I work for is neither capable of maintaining own Qt builds (not enough man power) neither willing to go with commercial license mainly because we do comply with LGPL and we use <1% of the Qt Framework.

I guess the GOOD news is, since version 6, CMake will be the default build system, see: https://www.qt.io/blog/qt-6-build-system

This is not true to my knowledge. Open source users get binaries for all major Qt versions (like 5.15). What they do not get are bug fix releases (last number in version number like x in 5.15.x).

I know it's not really an installer but you can download the releases in .zip format from https://download.qt.io/online/qtsdkrepository/ (you need to navigate to the correct subdir for your system and target) then you just uncompress them without the need on a connection. There is also a python script that simplifies the download and allows you to automate it

@jsulm So where can I get an installer for 5.15.0 ? Not from here: https://download.qt.io/official_releases/qt/5.15/

[jsulm]

@pip010 You can get it using online installer. Offline installer is now only for commercial users for newer versions as far as I know.
