Hi,
Did you check that you have enough space on your hard drive ?

Yeap, I have enough space. I also tried the offline installer but I get the same error.

Hi, looks like DEP fault (Stackhash_0a9e), try disable it in a CMD window (started as a Administrator):
bcdedit.exe /set {current} nx AlwaysOffMore here

I tried that but it didn't work. I don't think that's the problem anyway, the installer is clearly trying to reference a null pointer.

Hi, the code is legit, however in the .exe file those bytes can be found pretty close to the start of the file (around offset 0xaaaa0). Also on my Win7 that code at 0x0118B1AF isn't the same as yours (when I break the installer at 0%).
Hmmm could it be an anti-virus program like Avast that's reshuffling your Qt installer? -

Ok, after some research I found the problem. The installer was failing to load the module kernel32. To load the module it first calls the Windows function LoadLibrary passing the filename “kernel32.dll.dll” for some reason. When this fails it tries again with “kernel32.dll”, except that it only does so when the function GetLastError returns ERROR_MOD_NOT_FOUND (0x7E). If the first call to LoadLibrary fails for some other reason the installer doesn’t retry. In my case GetLastError was returning ERROR_NOT_READY (0x15). This occurred because my PATH contained a reference to a folder on the D drive that used to be a disk partition but now is a DVD drive that was empty at the time:
After removing that folder from my PATH the installation completes successfully.
This is probably a bug. The installer shouldn't use the value returned by GetLastError to determine if LoadLibrary failed.

Thank you very much, Primer!
Searched quite a while for this. Obviously it is still a Topic on Windows 7. -

I am sorry to open this old topic but I was facing same problem just now (Apr 14, 2020) on quite old computer with windows 7. I am using this version of the installer qt-unified-windows-x86-3.2.2-online.exe and "stuck" just before installation process to start. So I decided to try Primer solution about the "kernel32.dll.dll" file not found. I made a copy of the file "kernel32.dll" in folders windows\system32\ and windows\sysWOW64\ and rename the copied files like the missing one "kernel32.dll.dll" and the installer just continue with the installation.
Thank you Primer for your research!
