@Axel-Spoerl

so I found this in the maintenance tool:

can you please explain it to me? Do I need to use MS visual studio if i want to use the webengine module on windows? and it won't work in Qt creator on windows?

[jsulm]

@Aronox Yes, you need Microsoft compiler for Chromium.

[Aronox]

@jsulm thank you for your response.

So can I use qmake in Visual Studio? or do i need to switch to cmake?

[jsulm]

You don't have to use Visual Studio at all. In fact you do not even have to install it - MS Build Tools is enough. QtCreator will detect MS compiler if you install either Visual Studio or Build Tools.

[Aronox]

@jsulm oh so i just have to switch the compiler form MinGW to MS Build Tools?

[jsulm]

Well, you also have to install Qt for Microsoft compiler

[Aronox]

@jsulm Sorry I didn't get it 😅. I'm super new to this. is it this one?

but I have 6.7 installed not 6.7.1

[jsulm]

@Aronox said in Web engine not installing or downloading properly:

is it this one?

Yes

"but I have 6.7 installed not 6.7.1" - why not upgrade to 6.7.1? But you should also have MSVC for 6.7.0.

@jsulm one more thing:

this is a screenshot of Qt installed on my friend's windows 11 machine. He has the module which is 6.5GB. Does it mean that for me, I cannot have the module with windows 10 but on windows 11 it is possible? my main problem is that webengine module is 0 bytes on my windows 10 machine.

again thank you very much, you don't know how long I have been trying to fix this.

[Aronox]

@jsulm unfortunately I don't have any MSVC option in the 6.7.0 version

[jsulm]

I doubt it has anything to do with Windows version. If it shows 0 bytes then I guess the installation failed.

[Aronox]

@jsulm I have tried deselecting (removing the component) and then reselect it after launching the maintenance tool. It stays at 0 bytes. Should I try by completely removing Qt and doing a reinstallation? And after I get the module installed, I still have to use MSVC instead of MinGW to build, right?

If you want to use Qt Web Engine then yes.

You can try to uninstall everything and install again.

[Aronox]

@jsulm Hello !

Just wanted to update you that i got it working after installing MSVC. But now i have another problem.

The browser is freakingly slow,

but the same program on my mac has way better reasults:

so do you know anything about this? what do i need to optimize it?

[SGaist]

Hi,

Are you using a debug or a release build ?

[Aronox]

@SGaist on both systems i am using debug build.

@Aronox
QWebEngine is known to be particularly slow in Debug builds. Although I understand you are only interested in the difference in speed between the two, it would be interesting to see what that is on a Release build instead.
