I can't run QT on Windows 7

Hello, I can not run QT on Windows 7. QT doesnt start.

Hi, just a guess, but if you have an antivirus program running, try disabling that.

Sergio79

I have already try this.

hskoglund

When you try starting Qt, do you get an error message?

Sergio79

@Sergio79 Qt start in Windows "Services" and stop after 10 seconds. I tried to install an remove it three time ysterday . Allways the same result.

hskoglund

Hmm what version of Qt is that?
Also, to make sure, this is not Apple QuickTime that won't start?

Sergio79

@hskoglund no error message. the hard disk start and stop afert 10 seconds. nothing on the screen

Sergio79

it's this one : Qt 5.5.1 for Windows 32-bit (MinGW 4.9.2, 1.0 GB) I don't have Apple QuickTime on my computer. Yesterday i could start QT one time, but i don't know how

hskoglund

Maybe if you try to start it from a CMD window there will be an error message, try:

cd /d C:\Qt\Qt5.5.1\Tools\QtCreator\bin
qtcreator.exe

(Note: I'm guessing the file path to your Qt Creator, it could be slightly different.)

This usually happens when your graphics card does not support high enough OpenGL version. Try running Qt Creator with OpenGL plugins disabled like this:

<path to your installation dir>\qtcreator.exe -noload Welcome -noload QmlDesigner -noload QmlProfiler

Btw. QT stands for "Apple Quick Time", Qt is a name of a library and you're having problems running Qt Creator, not Qt.

@Chris-Kawa Thank you very much, it worked for me!
The Qt Creator is working yesterday, but today is not alright. It issues Qt Creator has stopped working.
So I think my graphics card can support OpenGL version, but it's driver is not good enough.
By the way, I have an antivirus program running and scan computer yesterday.
Is my understanding right, please?
Could you help me, please?
Best Regards!

I have fixed the problem: uninstall the graphics card driver and then re-install it.
