Since Qt6 does not support Windows 7 anymore you have to choose an older qt installer from e.g. https://mirror.netcologne.de/qtproject/archive/online_installers/

@jsulm @sierdzio Thank you both so much. I will try that out.

@JKSH

I did the download overnight anyway so I don't need further help resolving it, but I'll do that post on the Development mailing list to help others.

...unfortunately it is no longer possible to manually choose a mirror in the online installer.

Post the download speed you get from your default mirror, compared with the download speed you get from the best mirror you can find manually.

I'm confused, if I'm unable to manually choose the mirror in the installer, am I supposed to test my best mirror speed on the offline sources instead?

If I manually select http://mirrors.ocf.berkeley.edu/ today I can get ~1 MiB/s.

Presumably from the offline mirrors? Using the same mirror only gave me 330KBps.

The smallest possible download is a few hundred MB, which can be feasibly downloaded on a 200 KiB/s link.

The MSVC 2019 32 and 64 bit for Qt 5.15 are each 7GB so that's what I meant by smallest possible download.

@bdfyy You can use this tool: https://github.com/JKSH/QtSdkRepoChooser

Hi Patrick. I'm in the same situation. Installation on archlinux using the official qt5.13 online installer. Android and desktop kits are well configured on qtcreator just by using their respectif qmake. However when I choose the one.of webassembly (wasm_32) distributed by qt, qtcreator warns about the ABI, saying that it is not defined. Its value is unknown-unknown-unknown-.....

I compiled a simple qt project using wasm_32 kit but link fails with the following error main.o: architecture machine must be wasm32.

Any help?
