How to install module "QtMultimedia" on Windows

I've configurated only the Desktop kit as follows. Also, the Help menu says I'm using 5.15 while the kit is 6! I don't know which one is more correct! :|

@qcoderpro As I suspected, you are confusing the version with which QtCreator was compiled (5.15.2) with the Qt you have installed (Qt 6.0.0). If you analyze the second image you will see that "C:/Qt/6.0.0/mingw81_64/lib/..." says where it is concluded that you are using Qt 6.0.0. Solution: Download Qt5 and remove Qt6 so you don't have that kind of problem

the version with which QtCreator was compiled (5.15.2) with the Qt you have installed (Qt 6.0.0).

Can't we have Qt 6 for both the compiled and installed versions to get rid of this problem and also have the most up-to-date Qt version?

Download Qt5 and remove Qt6 so you don't have that kind of problem

You mean to unselect Qt 6.0.0 and select Qt 5.15.2?
So what are those Qt 6.0.0 and Qt 6.0.1 for?

@qcoderpro I recommend you select 5.15.2 and deselect Qt 6.0.0.

Qt 6.x.y is a new version (with many internal changes) but so far the multimedia module has not been added. See this https://stackoverflow.com/questions/65213872/qt6-and-multimedia-module.

No, it says what Qt version was used to build QtCreator, not what Qt you're using.

Thanks.

No, it says what Qt version was used to build QtCreator, not what Qt you're using.

So is the proper way to see the Qt version installed to look at the version of the kits' Qt, please?

Yes

One more question.
Should we update Qt to the latest version (Qt6 or 6.1) to be able to use QtQuick3D? If so, how to use libraries like QtMultimedia which are not supported in those up-to-date versions yet? :(

Qt Quick 3D is available in Qt 5.15: https://doc.qt.io/qt-5/qtquick3d-index.html

I'm trying to implement the following example of this page but get errors!

Did you install the Qt Quick 3D module?

Open your MaintenanceTool and select "Add Components". Select Qt > Qt 5.15.2 > Qt Quick 3D

Probably still can't be done using 5.15.2!

I just realized that you're trying to use Instanced Rendering.
This feature is only available from Qt 6.1 onwards: https://www.qt.io/blog/qtquick3d-instanced-rendering

Qt 6.1 is not yet released.

Have a look at the link I posted before; it contains examples that work with Qt 5.15.2.
