Installing Qt without commercial license

tdc0311

Hi, so a year ago i use Qt under a educational license, and now that license has expired. Is there a way i can still use Qt along with Qt Creator and its modules without buying a commercial license? I've looked for offline installer in Qt websites but there're only source packages and Qt Creator community (i've downloaded this and it didn't find the MinGW build). Very appreciated for your help!

Hi ans welcome to devnet,

You can use the online installer. With it you can install Qt Creator as well as other tools and the Qt versions you want (outside of the commercial only LTS releases).

Offline installers are now for commercial users only.

@SGaist hi and thanks for your answer, but now i have another question, hope you can help me! So i just downloaded the Qt
6.7 via online installer but i can't find the MinGW 32 bit version, can you show me where it is because the project i am working on was built in 5.15.15 MinGW 32 bit, hope you can help me. Thanh you and have a good day! Screenshot 2024-05-24 002142.png

I think read

https://forum.qt.io/topic/123896/qt-6-can-t-find-32-bit-components-in-setup

In short I don't think you get MinGW or anything else 32-bit at Qt 6+.

@JonB is there any way i can move back to 5.15.15 and still use Qt Creator and its tools, because i need to build my app in MinGW 32 bit. Thank you!

@tdc0311
Well, yes, you can install Qt 5.15 and use that. You will have to look around a bit to find where you can still install it from. There are a couple of posts saying it's a bit hard to find, e.g. https://forum.qt.io/topic/156830/qt-5-x-not-showing-up-in-online-installer and https://forum.qt.io/topic/156826/help-with-nstallation-of-qt-5-haven-t-found-online-installer-for-qt-5-versions-in-2024.

@JonB thank you but i still can't find where to download the 5.15.15 version haha. But i found the 5.12.12 online installer in the archive and i think i'll stick to that version from now on. Thanh you for your help and have a great day!

You can't as it's not yet released as open-source. And even then you would have to compile it by yourself from source.

@tdc0311 i don't know if something is wrong with your installer but i have qt5.15 here

@Ronel_qtmaster
The OP asked for Qt 5.15.15, you show version up to 5.15.2.

Be aware too that recently there was a long discussions where apparently versions like 5.15.x seemed to be available for download to some people but not others, perhaps depending on their platform. I don't know whether anyone figured out definitively what was going on.
