No Qt platform plugin could be initialized

[ham13]

Regarding OneDrive. OneDrive will not run. It since it thinks the OS is win 8.1 it will not start unless I update windows. Windows update has no available updates as the OS is now Win 10. I downloaded the current OneDrive but it will not install. It tells me "You have an preinstalled app for this". Seems like catch 22. Should I copy the OneDrive offline files for BU the uninstall OneDrive using the programs/app from the control panel?

I'll post the output of the debugger later today.

Thanks

I have no idea. Maybe you are supposed to uninstall the existing one first. You should not need to use some Win8 OneDrive client under Win10. But like I said, I am not making any promises, only assumptions.

Should I copy the OneDrive offline files for BU the uninstall OneDrive using the programs/app from the control panel?

If you have the space somewhere it might be a sensible precaution :)

[ham13]

Ok on OneDrive. Will BU files the delete them from OneDrive.

The results of the debug are below.

Hi it's complaining about the C:\Qt5\Tools\QtCreator\bin\plugins\platforms\qwindows.dll file, that it's a not a valid .dll. Do you have any 3rd party antivirus program like Avast installed?
Also check the size and date of that file, mine looks like this:

C:\Qt\Tools\QtCreator\bin\plugins\platforms>dir qwindows.dll
 Volume in drive C has no label.
 Volume Serial Number is 2468-E241

qt.core.plugin.loader: QLibraryPrivate::loadPlugin failed on "C:/Qt5/Tools/QtCreator/bin/plugins/platforms/qwindows.dll" :
"Cannot load library C:\Qt5\Tools\QtCreator\bin\plugins\platforms\qwindows.dll:
The specified procedure could not be found."

It's not actually complaining that it cannot load the DLL per se, it's saying that it could not find the exported procedure it was asking for/expecting to find. Unfortunately we don't know which procedure name. Not that it helps much solve why/what to do.

[hskoglund]

If you disable TrendMicro do you get the same error?

Edit: forgot to say, it could be you're missing some stuff from Microsoft that qwindows.dll needs to load ok, I'm thinking about the Visual C++ redistrubuable files (early versions of Windows 10 do not have them). Go here to install and choose the X64 flavor.

[ham13]

Same error with antivirus (TrendMicro) off or on. Installed Visual C++ redistributable 64 bit. No change. I get same error on both Qt6 and qt5. I have installedQt5 in \Qt5. Maybe I should have installed it in C:?

Thanks

[hskoglund]

Hi, you could try launching Qt Creator without loading or requiring qwindows.dll, open a CMD window:
C:\Qt5\Tools\QtCreator\bin\qtcreator.exe -platform direct2d

If that fails: the problem could be some detritus from previous Qt versions that still remains. One way to test that is if you create a new user on your PC, log out and log in as that new user. Then try start Qt Creator on that desktop (if there's no icon to launch it you might have to navigate to the qtcreator.exe file manually).

*Edit": also a good test of Qt's health is to run qtdiag.exe from a CMD window. (There's usually 2 of them for a given Qt release, one in the mscv2019\bin subdirectory and one in Qt\Tools\QtCreator\bin so try running all 4 of them :-)

[ham13]

Ran C:\Qt5\Tools\QtCreator\bin\qtcreator.exe -platform direct2d. Got same error.
Tried new Windows user. No change.

Found qtdiag in Qt5\5.15.2\msvc2015-64\bin. Found QtAsistant, QtDesigner and QtLinguist in this directory and all three ran. Unfortunately Result below QtCreator was not there. Maybe these are leftover from a previous install? the do not show up in "Programs and features". How should I clean them out?

Aha, I think the mystery is solved: qtdiag.exe says that you're in fact running Windows 8.1 and not Windows 10.
That explains why Qt 5.15.2 works except for Qt Creator 8.0.1 which is based on Qt 6.3.1. And Qt 6.3.1 does not run on Windows 8.1, it requires Windows 10 or 11.

To get a working Qt Creator, you can install a version of Qt Creator based on Qt 5. 15.2 from here: https://download.qt.io/snapshots/qtcreator_qt5/8.0/8.0.2/307/qt-creator-opensource-windows-x86_64-8.0.2_307.exe

OK. That was the problem. I downloaded and installed QtCreator 8.0.2 as you suggested. It loads and runs. I'll test it out with a project later. So it looks like I should continue with Qt 5.1 and not use Qt 6 unless I have a "real" Win 10 PC.

That also explains why I cannot use or upgrade MS OneDrive. There are no updates to Win 8.1 available. The PC just wants to see updates to Win 10.

My question it is true that the PC originally had Win 8 installed when we purchased it. Then MS came out with the free update to Win 10. We applied that update. We thought that it updated to Win 10 and I have added software based on that assumption. So which is it Win 8 or Win 10 or some
combination of both? Do I consider the OS to be Win 8 or Win 10?

Thank you for your patience and help! I never would have figured it out without you advice.

Thanks

Which one does it look like? If it didn't look any different at all after "upgrading" didn't that concern you? :)

How about: File Explorer, right-click on This PC, Properties. What does it tell you about your edition of Windows?

Thank you all for your responses! I installed Qt and QtCreator using the Qt installer I downloaded from the Qt site. Installed both Qt5 and Qt6 separately
