windeployqt, looks ok, but no files transferred

[SPlatten]

@KroMignon , why is because I didn't realise it would do this, I thought the default search criteria for DLL's is first to look in the local folder then to search the Windows folder, I don't know how or why its looking in the Qt installation folder?

[SPlatten]

@KroMignon Where does the qt.conf file go? In the same location as the EXE ?

NVM, read from documentation.

The way Qt is searching plugins is well documented (cf. https://doc.qt.io/qt-5/deployment-plugins.html).
This is why I asked you what you have done:

• set QT_PLUGIN_PATH ?
• defining a qt.conf file (cf. https://doc.qt.io/qt-5/qt-conf.html)?
• by code with QCoreApplication::setLibraryPaths() or QCoreApplication::addLibraryPath()?

@KroMignon , I've created local qt.conf:

[Paths]
Plugins=.

This seems to have done the trick as the debug.txt reports the correct location is now being searched:

Reinstalling the application may fix this problem.

I've checked the that qwindows.dll is present, why can't it load the library?

It looks like this error relates to the EXE architecture being not compatible, the EXE is win32. I thought I had transferred the correct DLL's for win32, will check again.

Checked again, dll is the win32 version but still getting this message in the debug.txt ???

There is something very strange on your configuration.
Are you sure you are using same Qt-Kit as kit used to build the binary?
Can you run the binary with Qt Creator in release mode?

[SPlatten]

@KroMignon , thats the odd thing...I can't even run it though Qt Creator in release mode, the only difference is that the message appears in a dialog...debug works fine.

This means you Qt Kit is corrupted... The only way would be to reinstall it, I guess or use a newer one.

[SPlatten]

@KroMignon thank you, will see what can be done....for now I'm going to get it working using the debug libraries, I know these are ok, then the release dll's can be used later.

[SPlatten]

@KroMignon , have got working release dll's and now it all works, thanks for your support.
