Qt WebEngine installation via Maintenance Tool freezes

[Lunix]

Hello everyone,

I'm encountering an issue while trying to install Qt WebEngine Source component, using the Qt Maintenance Tool. I'm using Qt 6.9.0 MSVC2022 64 bits. The component is in Extensions > Qt WebEgine > Qt 6.9.0 > Sources.

The installation process consistently freezes at around 69% during the extraction of the file:

6.9.0-06202503301021qtwebengine-everywhere-src-6.9.0.zip

I have tried multiple times, but the problem persists. I have checked my internet connection and disk space, but everything seems fine.

Has anyone else experienced a similar issue, or does anyone have suggestions on how to resolve this? Are there alternative ways to install Qt WebEngine if the Maintenance Tool is failing?

Thanks in advance for any help.

Hi,

Did you already try to change mirror ?

[Lunix]

@SGaist yes, I tried this one : https://www.nic.funet.fi/pub/mirrors/download.qt-project.org/ but same issues happend.

Strange...

Do you have the same issue if you try to install 6.8.2 for example ?

[Lunix]

@SGaist I just tried downloading version 6.8.3, and the Maintenance Tool successfully installed it!
During the installation, this file was blocked by Avast:
D:\Progr\Qt\6.8.3\Src\qtwebengine\src\3rdparty\chromium\components\security_interstitials\core\browser\resources\interstitial_large.html

It froze at 65%. I added an exception for the file and temporarily disabled my antivirus. After that, it worked.

I restored and added exceptions for all files related to Qt, disabled my firewall, cleared the cache, ran the Maintenance Tool as administrator, and now I'm trying to download version 6.9.0 again. If it doesn't work, I don't know what else I can do except trying to force a manual installation.

P.S.: I also previously updated Windows and my GPU drivers, but that didn't change anything.

Antivirus are often getting in the way of development 😅
I hope 6.9 gets successfully installed now.

@SGaist It's resolved ! Finally ! Disabling my antivirus, firewall, and clearing the cache fixed the issue. Thanks for the help! Now I have other problems with WebEngine, haha.
