"could not find or load the Qt platform plugin "windows" in "",



  • Hi,
    I'm dealing with this error message when I want to run my Qt program (installed on Windows 7 x64). I found this thread and wanted to reply there but the forum suggested creating a new one so I came here.

    My cmd echo is this:

    0_1547458901901_Capture.PNG

    There is a platforms folder in the path but it hasn't a qwindows.dll
    Should I remove that path from Path?

    What could be the problem?
    Do I need to install the MiKTeX program to fix this issue?



  • did you use windeployqt?



  • @VRonin
    Apparently it's used to create a folder containing the installable program. But I have produced the installable file using Qt Installer Framework previously. And it could be installed on Windows and run well.
    Recently I added some new paths to the Path and changed it that way, for example for Gradle and now after installing the program and when double clicking on its icon, I get the error.

    Do you still think the windeployqt.exe tool can be helpful?
