    Where did you install the plugins ?
    You can also set the QT_DEBUG_PLUGINS environment variable to 1 in the Run part of the Project panel to see what is happening.

      @SGaist The .desktop files are in the files and programs folder, the libs continued in the folder on I compiled, which was in C: / Git / kimageformat / build, and the dll were for the qt compiler itself, msvc2017-64 in the plugin / image folder

      One more thing, in this directory "C: \ Qt \ 5.12.0 \ msvc2017_64 \ plugins \ imageformats", I realized that the "tga" format, had tbm support here, and gives the same error when I try to open open exr in the app debug "QImage :: scaleWidth: Image is a null image".

      First I used the .dll, .pdb files with this name "kimg_exr", then renamed "qexr", both the dll and the pdb, but it still did not work, nor with the native tga that worked right.

      And if it is useful these are my includes

      #include "mainwindow.h"
#include "ui_mainwindow.h"
#include <QDesktopServices>
#include <QMessageBox>
#include <QUrl>
#include <QFile>
#include <QFileDialog>
#include <QImage>
#include <QPixmap>
#include <QImageIOPlugin>
#include <QImageIOHandler>

        Did you call nmake install at some point ?

            Then this might explain the missing plugins.

              @SGaist So I'm practically going to have to build manually?

                Build what manually ?

                The fact that you didn't call nmake install after building the module just means that you didn't install the libraries/plugins you built so that might be a reason why Qt can't find them. You should first try that.

                    Did you run your application with the QT_DEBUG_PLUGINS environment variable set to 1 to see what exactly is happening with the plugins ?

                        Might be a silly remark but the casing is important as well as the name. It's QT_DEBUG_PLUGINS not q_debug_plugin.

                          @SGaist In fact I researched this way, but even so I did not this option, nor to implement in code
