QT_QPA_PLATFORM_PLUGIN_PATH trouble

[KLWEBA]

I run TS3, Qt Creator and Qt 5.5. The QtC installation sets QT_QPA_PLATFORM_PLUGIN_PATH to its corresponding path. This causes Teamspeak 3 (64bit, on Win10) to fail: "This application failed to start because it could not find the platform plugin windows."

When I disable QT_QPA_PLATFORM_PLUGIN_PATH then TS3 works, but QtC/Qt does not anymore. My problem: We use TS3 along with Qt presentations. Any idea how to overcome the problem?

Hm, haven't had that happen yet.
What's not running exactly? QtCreator itself or the compiled programms?
In the later case you could deploy to your appdir/platforms or add (http://doc.qt.io/qt-5/qcoreapplicati...addLibraryPath) or set (http://doc.qt.io/qt-5/qcoreapplicati...etLibraryPaths) a custom path.

Please consider to add a file to teamspeak folder.
https://doc.qt.io/qt-5/qt-conf.html

Add the file named qt.conf with the following content:

[Paths]
Plugins = .

After adding this file to the binary-folder, your teamspeak-client should start again.

Please consider to add a file to teamspeak folder.

Good hint, thanks. The second solution I have found is to add QT_QPA_PLATFORM_PLUGIN_PATH only under QtC`s Project Build environment.

Solved.
