Install old Qt-5.9.9 opensource

[JNBJNB]

Hello all,
I would like to install Qt-5.9.9 opensource in my public laboratory.
I downloaded the
qt-opensource-linux-x64-5.9.9.run installation tool which asks me to choose between 2 licenses.
I need qt-5.9.9 because I hope I will be able to build a soft which maybe needs that kind of old Qt version.
=> Would you please tell me which license I must use ?
Thanks in advance for your help.
Yours,

JNB

Hi and welcome to devnet,

That depends on your project and it's own licence.

To install Qt 5.9.9 Open Source, you can download the source code from the Qt Project website and build it yourself. Alternatively, you can download the pre-built binaries from the Qt Downloads page.

@JNBJNB Since you mentioned that you want to use Qt-5.9.9 for building a software in your public laboratory, you should select the open source license option when prompted by the installation tool. The open source license allows you to use, modify and distribute the software freely in accordance with the terms of the license agreement.

If you are unsure about which license to choose, you can refer to the Qt licensing page for more information: https://www.qt.io/licensing/

I hope this helps. Let me know if you have any further questions!
