Qt crash at installation

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.

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)

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.

Great! Happy coding.

sunhouzi

@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).

sunhouzi

@JKSH I try disable antivirus, it still crash.
can you feedback this problem to developer? i can upload log if need.

You can do it also: https://bugreports.qt.io/secure/Dashboard.jspa

sunhouzi

@jsulm ok, think you~

@sunhouzi Did you fix it eventually? I have the same problem where I can't install qt. The system log also says error unknown

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.
