Qt crash at installation

Fasstaff

@JKSH
Hello Thanks for your answer.

Yes, it is working an my laptop, though I want it on this computer, not the other one.
So using the other one is not really an option.
Could it be my firewall maybe ? or anything security wise ?

Hi, does it still crash if you try installing Qt to some location other than C:\Qt?

Fasstaff

@LeLev

Yeah, it does (never gone to look at that before)

it says that : (It's in french though, ask if translation is necessary)

Hello,
I'm trying to install it in my E: drive so yeah, it does

hskoglund

Ok let me rephrase the question: does it still crash if you try to install to C:\Qt?

Fasstaff

@hskoglund

I just tried and yes it crash too

hskoglund

Hmm it could be something hazardous in your PATH settings, you could try open a CMD window with the PATH temporarily set to empty:

set path=
E:\Téléchargements\qt-unified-windows-x86-3.2.1-2-online.exe

Fasstaff

@hskoglund Sorry for not knowing it, but what would setting a path do ?

JonB

@Fasstaff
The code is clearing the path environment variable to try to ensure the installer doesn't try to load/run/find something elsewhere that it's not supposed to.

But it doesn't matter unless you try @hskoglund 2 lines (exactly as shown) in a Command Prompt. See if that makes it work or whether you have the same crash.

Fasstaff

@hskoglund
Oh, I don't know why but this solve my problem, thank you very very much !

Though, if possible, I would still like the explanation ^^

The PATH is a list of folders. Windows tells your executable to find and load DLLs from the PATH folders.

If clearing the PATH stops a program from crashing, then you probably have a case of DLL Hell. One of the folders in your PATH probably contains DLLs that are incompatible with the Qt installer (for example, it might contain a different version of Qt DLLs)

For this reason, we should avoid adding items to the PATH unnecessarily (and we should design our software in a way that doesn't need to be put in the PATH)

Fasstaff

@JKSH
Thank you very much for the explanation !
And yeah, marking the topic as solved !

Hi, and welcome!

Do you have another PC? Can you try running the installer on a different PC?

Unfortunately, the log doesn't say what caused the crash.

OK, can you try installing on another PC? Does it crash there?

i change video

Thanks. So the installer can start, but it crashes after you select the items you want to install. Unfortunately, I have never seen a crash at that step before, so I can't say what's causing it. My guess is that something in your OS settings (or antivirus settings) is interfering with the installer.

@JKSH i install qt in virtual box on crashed pc, install success.
