Windows 10 has restarted my machine without my consent

This can be prevented, you know. There are settings for that.

@artwaw
Maybe, but Win 10 does tend to have a "I know better than you" attitude, compared to Win 7 ;-)

So I make sure my PC cannot be reached from internet, does not have any email capability and only surf to qt.io and google.

lol. Henry, I'ven't taken you as one of them tinfoil-hat people ... ;)

hskoglund

Don't worry @kshegunov , no hat for me. But those ancient Windows installations you have to treat gently so they don't break :-)

Thank you,you save me!

@hskoglund : There are Qt 5 based builds of Qt Creator 6.0.x on https://download.qt.io/snapshots/qtcreator_qt5/6.0/

hskoglund

@andr Thank you! I know I've seen that link before but couldn't find it.

If those Qt5-flavored builds of Qt Creator keep coming, that'll solve almost all of my issues with Qt and Windows 7, except if I want to build and test a Qt6 app. In that case my patches above could still be useful :-)

@hskoglund Will you like to share the patches that you had applied to fix this 0xC0000005 error? I am also trying to get 6.2 working on Windows 7. Even the uic.exe moc.exe console apps fail with 0xC0000005 error. Many Thanks if you can help out.

Hi, the patches for Qt 6.2.2 in binary format (3 .dlls) can be downloaded via the link above (in the first post).
The patches in source format consists of 9 files, I made a .zip for you here
I've only tested them on Qt 6.2.2 but with a bit of luck they should work on 6.2.3 as well...

I still find Win 7 much better than Win 10. But at some point one has no other options than update.

hskoglund

@jcga Agreed. I upgraded my PC from Windows 7 to Hackintosh MacOS Montery :-)

@hskoglund sup , i dmd you ...need your help for some QT .dlls , to get some 6.2.2 and 6.2.4 apps to work with w7, much obliged

subalternpushingtech29087

@jcga theres still life left yet my good dude , ESUS still go till end of this year , still solid shit

hskoglund

Hi, you should be able to get a Qt 6.2.2 MSVC 2019 64-bit widgets-flavored Qt app running on Windows 7 by downloading the .zip (link in the top post) and replace those 3 .dlls in your Qt installation.
For a Qt 6.2.4 widgets app it is likely to get it to work (I haven't tried) on Windows 7 by downloading the source .zip (see link above), replacing the 9 source files and rebuilding Qt.

@hskoglund would appreciate it if you could give it a look , 6.2.4 .dlls , when you have some time of course, im not good at all in terms of rebuilding QT, just aim to run QT 6.2.2 and 6.2.4 apps on w7, tho if theres a easy one click tool that does this ...i can try, mind you i dont have QT installed myself , but the apps i use have QT included aka use QT and its .dlls , as ive posted an example in the Chat i opened with you

subalternpushingtech29087

@hskoglund , would still appreciate if you could help a bro out here...as said i posted you one of the apps i use also in chat .....also if you have discord id like to add you to my friends list

hskoglund

Sorry I'm swamped with work now, but when Qt 6.3.0 arrives I might give it a shot re. Windows 7...

subalternpushingtech29087

@hskoglund very nice my man , appreciate it alot!

@hskoglund Build error, Qt 6.3.

dmginc

With some initial guidance from @hskoglund (thanks!), I have managed to create Windows 7-compatible DLLs for Qt 6.3.0 (QtCore, QtGui, qwindows).

Purely for experimental/"at your own risk" use of course :)

Download for DLLs (also contains diff file showing the modifications needed to the original source files): https://web.tresorit.com/l/idV8c#QwlBcUwvkQYjzbRSWlZlnQ

Any issues, please let me know.
