Qt creator (with bundled 32bit minGW) does not work after Windows reinstallation

Aaron Kim

Hello, I had suffered from blue screens recently, so I reinstalled Windows 10 yesterday, with a latest Qt.
However, I found that even a single default project can not be run on the Qt creator.

After I searched this problem a little bit, I also found that MinGW bundled with Qt installation does not work

I strongly assume that this happens because it is 32bit (However, it worked fine before I reinstalled Windows)
I can not use 64-bit MinGW currently because it is not compatible with Qt, as well as the current project I'm working on uses 32-bit FMOD library. I'm quite frustrated now because I have to finish this project until next week.

I don't know if it can help to detect a problem, but it says that ABI detection is failed.

Qt version : 5.11.2 (latest)
Qt creator : 4.7.0? I can't remember but it was installed with the latest Qt
MinGW : 5.3.0 32bit (bundled with Qt)
Windows 10, 64bit

What do I have to do? Should I try installing it with another, older Qt version?

It should not. We are using it and working fine. Can show your kits configuration ?

Aaron Kim

@dheerendra Here it is

jsulm

@Aaron-Kim To be sure: after you reainstalled Windows you reinstalled Qt? Or are you using same Qt installation?

@Aaron-Kim it seems you installed way too much and you are confused now.

Try installing only Qt for MinGW and the MinGW compiler.

You dont need the MSVC and UWP stuff.

@dheerendra @jsulm @aha_1980

I just found a serious problem. All the gcc stuffs bundled with Qt are not installed correctly. (0KB)
I try deleting them all, and then installing Qt again, but same.
Why does this happen?!

jsulm

@Aaron-Kim Do you have anti-virus software running?
Any warnings/errors during installation?
Did you try to install into a different directory?

Aaron Kim

@jsulm Windows defender is turned on. I'll try turning it off.

Aaron Kim

@jsulm Yes. It was because of Windows defender. All the mingw stuffs work fine. But I just found that also some Qt dlls (like Qt5Widgetsd.dll) are also corrupted.
Is there a way to simply install only Dlls without any stuff?

You should reinstall Qt

@jsulm I managed to solve the problem by using offline downloader.
But I got the following error.

qt.qpa.plugin: Could not find the Qt platform plugin "windows" in ""
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.
Available platform plugins are: minimal, offscreen, webgl.

Aaron Kim

@jsulm Never mind! Qwindows.dll was also corrupted. I replaced it with the new one.
