Qt platform plug-in missing

• I am trying to use new software but each time I try to open it up ,I get a message saying that no Qt platform plug-in could be initialized..
what is this ,where do I get it ?
Everything else on my PC works OK. I am using Windows 10.
The software was written by a person , software has to do with radio hobby related things. There are Qt commands in the software.

• Hello!

It could be this issue: https://forum.qt.io/topic/101157/no-qt-platform-plugin-could-be-initialized
Your application is `QML` or `Widgets`?

You can try my solution for `Qt Widgets` application. Add the code below to your project `.pro` file for your app, then click `Clean`, `Run qmake`, `Build`:

Widgets app:

``````QMAKE_POST_LINK = \$\$(QTDIR)/bin/windeployqt.exe \$\$shell_quote(\$\$DESTDIR/\$\$shell_quote(\$\$TARGET).exe) --no-compiler-runtime
``````

QML app:

``````QMAKE_POST_LINK = \$\$(QTDIR)/bin/windeployqt.exe \$\$shell_quote(\$\$DESTDIR/\$\$shell_quote(\$\$TARGET).exe) --qmldir \$\$shell_quote(\$\$(QTDIR)/qml) --no-compiler-runtime
``````

Also, check out the documentation for `windeployqt`: https://doc.qt.io/qt-5/windows-deployment.html

• Hi, and welcome!

I am trying to use new software

Where did you get the software from?

but each time I try to open it up ,I get a message saying that no Qt platform plug-in could be initialized..

This message is telling you that a Qt DLL could not be loaded correctly. However, we don't have enough information to tell you why your software failed to load the DLL.

The software was written by a person , software has to do with radio hobby related things. There are Qt commands in the software.

Can you contact this person? They should know how to fix the problem.
