I downloaded latest installation, and I cant start any app in bin directory. Here is error from hbdbu --------------------------- hbdbu --------------------------- This application failed to start because it could not find or load the Qt platform plugin 'windows'. Available platform plugins are: minimal, offscreen, windows. Reinstalling the application may fix this problem. --------------------------- OK --------------------------- I tried to put qwindows.dll from Qt installation, but it still doesn't work. Also, to compile app with this installation I must set SET HB_QT_MAJOR_VER=5 or else app will ask for Qt4 libs to link.

Dec 12, 2016. I have tried to update my TomTom START 60 using MyDrive as I have done many times previously (on Windows 10) but this time when I tried to connect I get a Windows error message stating 'This application failed to start because it could not find or load the qt platform plugin 'windows'. Reinstalling the. Nov 29, 2017. 'Application failed to start because it could not find or load the Qt platform plugin 'windows'. AMD Settings fails to launch: 'Application failed to.

(not needed, since the installation is Qt5 based, and Qt libs are there) Regards, Dusan Majkic Wings Software Luigi Ferraris 02:01. >Will investigate more. I compiled Validator.hbp from qtwidgets/test. With latest latest Qt 5.3 (MinGw4.82 - OpenGL) only those dlls are needed. (No need for platform plugin!) Validator.exe depends on and works with: Qt5Core.dll Qt5PrintSupport.dll Qt5Widgets.dll Qt5Gui.dll libstdc++-6.dll libwinpthread-1.dll libgcc_s_dw2-1.dll icudt52.dll icuin52.dll icuuc52.dll If I copy those dlls to qtcontribs/bin dir - everything works! This Qt version is without ANdroid.

It could be some Android related issuse (like OpenGL). I am downloading Android version to check that also. Luigi Ferraris 02:36. Hi Pritpal, congratulations! Question: I read about plugins and I understand that platform plugins can be loaded by 5 methods: 1.- from hard coded path into Qt5Core 2.- from plugins platform 3.- from path specified into 'qt.conf' plus ' platform' string 4.- from path specified in QT_QPA_PLUGIN_PATH environment variable plus ' platform' string 5.- from path added to QCoreApplication class but, with these methods isn't possible to load plugins from (I can be wrong!) How you did to achieve this behavior?

Thanks in advance CdQ. Hi Pritpal, >>And a good one though.

It should be easy, but bow such path will >>be known to HbQt at the run-time? ENDIF oCoreApplication:addLibrary( cPlatformPluginsFolder ) >>You mean to check such path pointed to by env variable: >>QT_EMBEDDED_PLATFORMS_PLUGINS? No, it is for not include this automatic mechanist into hbqt library (at hbqt make time), because platforms plugins occupy 1.5MB. Then, if QT_EMBEDDED_PLATFORMS_PLUGINS=NO is specified, platforms plugins should be managed manually outside exe Note: you can use: FUNCTION hbqt_getTempFolder() RETURN QStandardPaths():writableLocation( QStandardPaths_TempLocation ) instead of getEnv() and '/tmp', but I think that at QCoreApplication point, the QStandardPaths class wasn't initialized (maybe) Regards CdQ.

After having run my application successfully in Qt4.8 for a long time, I'm now trying to deploy it in QT5.1.0. Everything has built cleanly, Dependency Walker confirms that all of my dependencies (Qt5Cored.dll etc. - the 'd' because I'm initially trying to install a debug version) are present and correct, and I've copied the whole of the 'platforms' directory from the 'plugins' folder into the same directory as my executable.

However, when I try to start the program, I obtain the error message: 'Failed to load platform plugin 'windows'. Available platforms are: minimal offscreen windows' So it seems to want to have it both ways - it can't find 'windows', and yet 'windows' is one of the ones that it can find. Either way the program won't start. What can be causing this?
