Qt crash at installation
-
@hskoglund Sorry for not knowing it, but what would setting a path do ?
@Fasstaff
The code is clearing thepathenvironment 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.

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 -
@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)

Hi, and welcome!
Do you have another PC? Can you try running the installer on a different PC?

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 no. no. no, it is not resolve my problem.
i need install qt in origin pc not virtual box. virtual box is a test environment.

Then you need to find out what is causing the crash, because the problem is specific to your PC. I have never seen this type of crash in the installer before, so I'm sorry I can't really help you. The only suggestion I can think of is to disable your antivirus (if you have one).

This took me ages to fix but in the end I fixed this problem by:
Example Batch Script:
Here’s how you can create a batch script to clear the PATH and run the Qt installer:Open Notepad.
Copy and paste the following lines into Notepad:
batch
Copy code
@echo off
rem Clear the PATH environment variable
set PATH=
rem Run Qt installer
"InstallerPath/...."
Save the file with a .bat extension, for example, install_qt.bat.
Run the batch script by double-clicking it. This will open a Command Prompt window, clear the PATH, and then run the Qt installer.
Note:
Replace "InstallerPath/...." with the correct path to your Qt installer.
Ensure that the Qt installer file you're using is not corrupted and that you have downloaded it completely. -
