How to build for x32 if my app is made with x64 kits?

hskoglund

Hi, I'd just install the 32-bit versions of Qt and never bother with the 64-bit versions of Qt, because there are so many Windows installations that are still 32-bit.
(And the 32-bit version of Qt you can install and run on a 64-bit Windows, but not the other way around.)

Forgot to say, Visual Studio 2019 (and as I heard also Visual Studio 2021) also follow this path, i.e. they are built as 32-bit applications that can run either on a 32-bit or 64-bit version of Windows.

please don't tell me that i don't have to download and install another same Qt but for x32 version.

Bingo!

As i understand i can not install it from MaintainTool, only download raw setup file from some site?

Okay, i'm done. I downloaded that 3gb, installed another Qt(same 5.12.0 version but x32) file name was: qt-opensource-windows-x86-5.12.0.exe it installed about 0.5gb in selected folder(interesting why weight of install file almost 3gb). And after all this i can't select bloody executable file when try to add Qt version!

UPDATE:

Just realised that i need qmake.exe file, and there is no such thing in whole folder of freshly installed x32 Qt!

What you are showing in your images is Qt Creator, not Qt

What should it be then?

Go to the folder where you installed Qt (not Qt Creator, it's where qmake.exe is) and start the maintenance tool, select "add or remove components" and tick the boxes as shown in the picture

@Nick111 You can use x86 on x64 if you don't really need x64
