Could not find the Qt platform plugin "windows"

[Deathcomes]

@SGaist Thank you! Already done that!

@Deathcomes said in Could not find the Qt platform plugin "windows":

It prints this

QFactoryLoader::QFactoryLoader() checking directory path "MY_PROJECT_PATH/release/platforms" ...

Is there a way to change this? It should by default be "C:\Qt\5.12.1\mingw73_64\plugins" right?

Is there a way to config this path? It should already be fine (tried it on other projects and it works ok (only difference is qt version)) but it seems not.

Have you put any other file to "MY_PROJECT_PATH/release" folder?
What if you completely delete that folder and try again?

[Deathcomes]

@Bonnie I always leave that folder as it so that i don't "break" something. I will check it although!

[Deathcomes]

@Bonnie I checked it and the same thing happens.

Hi, if you try run another Qt project from inside Qt Creator, like one of Qt's examples, do you get the same error?

[Deathcomes]

@hskoglund Theoretically no because i have another project (although with Qt5.2.1) which compiles and runs (from inside Qt) perfectly.
Should i try to test with a new project with 5.12.1?

[hskoglund]

Yes, try an example project with 5.12.1.

[Deathcomes]

@hskoglund Same thing happens with a new one.

[SGaist]

Do you have other versions of Qt installed on your system ? For example by other applications ?

[Deathcomes]

@SGaist Yes Qt 5.2.1 because i also maintain an older project.

These are my versions settings:

[SGaist]

I meant: check your system for other Qt version that may have been installed along any of your applications.

[Deathcomes]

@SGaist Ow! Sorry! How do i check that?

[Deathcomes]

@SGaist I searched but i didn't find any.

[Deathcomes]

Should i reinstall Qt 5.12.1 to possibly correct the problem?

[SGaist]

You can try that yes.

[Deathcomes]

@SGaist In what order should i install them in case the order is important? I repeat that i need Qt 5.2.1 and Qt 5.12.1.

[Deathcomes]

Reinstalling seems to have fixed the problem! Heck if i knew what was wrong! Can someone mark this issue as solved?

EDIT: Sorry! I found out how to mark my thread as solved! Thanks again for the help!
