Qt Creator 6.0.1 and Qt 6.2.2 running on Windows 7

[dmginc]

@bplastos

I took a look at the diff between Qt 6.3.0 and 6.3.1:

Out of the files that need to be modified for running under Windows 7, three source files have been modified: qwindowswindow.cpp, qrhid3d11.cpp, qwindowscontext.cpp

Anyway, I was apply to apply my 6.3.0 changes patch directly as there were no overlapping changes.

Could you try these DLLs under Windows 7?

I just compiled a new Qt 6.3.1 Widgets app and tested your 6.3.1 files on my Windows 7 PC. works like a charm :-)
Nice work!

I'd like to ask for someone to patch a bunch of dlls for me too (from dolphin-emu.org), but since it's an actively developing project, it means you have to patch 'em with every release.
So can I have a detailed tutorial and a list of needed tools to patch them myself?

[jsulm]

@HiXeus Is your post somehow related to this thread or to Qt at all?

[bplastos]

@dmginc Thank you very much for your efforts. Unfortunately, it made no difference in trying to get the latest versions of Calibre portable to run under Windows 7. There must be something else besides Qt changes that is preventing it from launching.

Hi, Calibre 6.1 uses Python 3.10 which does not work on Windows 7 :-(

@hskoglund and @bplastos
Use the QT6 files from the link above (great work btw) and then run Calibre using this: https://github.com/vxiiduu/VxKex in Win10 compatibility for calibre.exe It should work now just fine. At least it starts for me.

@Grdes - Please forgive my ignorance, but can you explain in detail, or point me to some detailed instructions, of how exactly to run Calibre using that project? And please be clear. Are you talking about running the portable version of Calibre (I hope)?

EDIT: I THINK I figured out how to install VxKex v0.0.0.2. I installed https://github.com/vxiiduu/VxKex/releases/download/Version0.0.0.2/KexSetup_x64Rel.exe. But still no success.

I installed https://download.calibre-ebook.com/6.0.0/calibre-portable-installer-6.0.0.exe, which seems to install. I replaced the Qt files with the latest patched Qt 6.3.1 files from @dmginc, then enabled VxKex for Calibre\calibre.exe and set it for Win 10 compatability. (Was that the ONLY file that needs VxKex enabled?) Again, nothing happens when I try to launch the app. Did you have to do anything to get around the Python 3.10 incompatibility issue?

EDIT2: Partial success! If I get a version of api-ms-win-core-path-l1-1-0.dll from here - https://github.com/nalexandru/api-ms-win-core-path-HACK/releases/download/0.3.1/api-ms-win-core-path-blender-0.3.1.zip - and copy it to Calibre\app\bin, then Calibre will indeed launch. But it won't do many of Calibre's functions. The eBook viewer doesn't work, it won't edit an eBook, nor will it convert to or from any of the eBook formats. I tried enabling VxKex for ALL of the Calibre exe files I could find, but no change. It launches, but doesn't really work. So a step in the right direction, but...

@jsulm Yes, the project uses QT and they recently moved from QT 5 to 6.

1. Download normal nonportable MSI Calibre Version: 6.1.0 installer from here:
   https://calibre-ebook.com/download_windows
2. Remove the Windows version check from the installer using SuperOrca MSI editor
   https://www.pantaray.com/msi_super_orca.html
   That means open the msi in SuperOrca, go to LaunchCondition and edit the Win version there or fully drop that row (right click, drop row) and save the edited msi file in SuperOrca as new file.
3. Install Calibre from edited installer without the win version check
4. Go to the installed Calibre folder and replace there QT files with the modified files from this topic.
   That means replace Qt6Core.dll and Qt6Gui.dll inside bin folder and also replace qwindows.dll inside plugins/platforms folder.
5. Right click calibre.exe and go the the VxKex tab. Enable here:
   a) Enable VxKex for this program
   b) Report a different version of Windows and set that to Windows 10
6. I have also copied the dll from api-ms-win-core-path-blender-0.3.1.zip to my Windows/System32 folder in the past, so maybe this has also some effect to this.

I didn't have much time to test Calibre functions yet, but I've tried to convert some PDF to MOBI and it works for me.

edit: but yeah the ebook editor and internal ebook viewer doesn't work for me as well. Those are external exe files and it doesn't launch at all. Maybe some more QT files needs to be patched?

Did anyone update the DLLs for 6.4.0 to run on Windows 7?

Thanks

@Perdrix

Here is a new set of DLLs for Qt 6.4.2: https://web.tresorit.com/l/TQOcz#l6c1gobdO3YraJvrU1SFuQ

Please let me know if there are any issues :)

@hskoglund said in Qt Creator 6.0.1 and Qt 6.2.2 running on Windows 7:

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...

Do you still have that patch zip somewhere? If you could share it, I'd sure appreciate it, as the old link is 404 here and on the Internet Archive.

[hskoglund]

@Darthagnon My bad I happened to delete it, it's back now.

[posktomten]

Thanks! @hskoglund
Now it is possible to run my program on Windows 7, for those who so wish!

Thank you so much!

[hskoglund]

@dmginc Still on my beloved Win7, couldn't get Qt Creator 9 to run.

Today I took the plunge and installed Qt Creator 10 beta 1. Turns out it's built with MSVC 6.4.2 i.e. a perfect match for your new set of DLLs.

And it works just fine :-)

@dmginc

Thank you for your helpful contributions!

Would you mind, please, providing patched DLLs for Qt 6.3.2 as well?

BTW, do you always recompile from patched
source, or is it perhaps possible to do binary patches using diffs for other versions?

[flaf]

@dmginc hello. would you mind explaining to me how you made the dlls work in windows 7? I would like to learn to be able to run some qt6 programs on Windows 7
