back around to the same problem again:

Do you have this error with the 64 bit or 32 bit version of your application?

SPlatten

@KroMignon , thats after installing with the 64 bit installer, I checked the DLL's and they look identical sizes to the 32 bit versions so I think they are the 32bit DLL's...but I can't run the application from the terminal.

Out of curiosity, did you try to check dependencies with dependencywalker?
It is ZIP archive, there is no need to install so you should be able to use it and check if there are missed dependencies.

No, not sure if I will be able to install it either.

It is a ZIP archive, you only have to extract it and run the exe. I think this should not be a problem.

SPlatten

@KroMignon , I've been having so many problems with windeployqt that I've chosen to try and do it another way, I've created a batch file and copied all the 32bit DLL's into the install folder:

@ECHO off
@ECHO Trainer Application Installer
REM Install services and applications
@ECHO Installing MariaDB
START /wait C:\Windows\System32\msiexec /i mariadb-10.5.9-win32.msi PASSWORD=PASSWORD SERVICENAME=MariaDB /qn
@ECHO Installing MySQL/MariaDB Connector-C 6.1.5
START /wait C:\Windows\System32\msiexec /i mysql-connector-c-6.1.5-win32.msi /qn
@ECHO Importing Trainer database from SQL source...
MYSQL -u root -pPassword --force < trainer.sql
@ECHO Installing Trainer application and dll's
SET INSTFLDR=%USERPROFILE%\Trainer
IF NOT EXIST %INSTFLDR% MKDIR %USERPROFILE%\Trainer
XCOPY *.* %INSTFLDR% /E /S
@ECHO Complete...

This works ok, MariaDB is installed as a service and running, the connector is installed and the database is imported from the SQL file.

When I try to launch the application I'm getting:

This application failed to start because it could not find or load the Qt platform plugin "windows"
in "".
 
Available platform plugins are: direct2d, minimal, offscreen, windows.
 
Reinstalling the application may fix this problem.

All the DLL's are in the same location as the EXE so what do I need to do now to satisfy this?

the problem here is the directory structure.
You also need to have the plugins in the right directory. The "brute force" way would be to copy the directory <qt_kit>/plugins content in to your install directory: copy /s/e/y %QT_KIT_DIR%\plugin\* %DEPLOY_DIR%

SPlatten

@KroMignon , when I first encountered this issue, the dll's were in individual directories, I moved them in an effort to fix it, it didn't.

Is your suggestion to recreate this structure? I don't see the environment variable QT_KIT_DIR. This was the original structure:

Sorry, I was a little bit 'untidy'. For me QT_KIT_DIR means the path to the Qt kit you have used to compile the binary:

@ECHO off

This directory struct is mandatory.
According to your error message there is no "qwindows.dll" in "platforms" sub-directory.

SPlatten

@KroMignon , ok, just done exactly that the entire tree structure is now present, still getting exactly the same result.

If plugin is present, then there are dll which cannot be loaded.
Try to set QT_DEBUG_PLUGINS and take a look at debug messages on console when starting the binary.
I would recommend to use a little batch script to start the binary and redirect output to text file:

set QT_DEBUG_PLUGINS=1
trnServer.eve > debug.txt 2>&1

@SPlatten The directory structure is explained here: https://doc.qt.io/qt-5/windows-deployment.html

This is your problem

SPlatten

@jsulm , I'm 99% sure the exe I am using is from the release build as its only 923KB, the debug version of the same is 1,637 KB.

@SPlatten said in windeployqt, looks ok, but no files transferred:

is from the release build

Then don't copy debug versions of the Qt libs/plug-ins, only release versions...

SPlatten

@jsulm , I haven't got any debug libraries ending with d.dll in the structure, confirmed this by using explorer with *d.dll in search platforms area.

Then what is this?

SPlatten

@jsulm , I really don't know how they got they're, perhaps on the last copy added from @KroMignon instruction? In anycase both the debug and the release dll's are in the same location, I will get rid of the debug dlls now.
