Cannot run online installer on Ubuntu 22.10

[ppitu]

Hi,
I try install qt creator on my new machine. I download from office website run file:
qt-unified-linux-x64-4.5.2-online.run

And now when I try run this I got this error:
./qt-unified-linux-x64-4.5.2-online.run: 1: ELF: not found
./qt-unified-linux-x64-4.5.2-online.run: 2: Syntax error: "(" unexpected

I have 64bit machine:

@ppitu Did you set the executable bit?

chmod u+x qt-unified-linux-x64-4.5.2-online.run

Another reason could be that the file is corrupted, then download it again.

[ppitu]

@jsulm Yes I use chmod +x qt-unified-linux-x64-4.5.2-online.run

I try download the file again but it want help and I still have this problem.

[jsulm]

@ppitu What is the file system where you store the installer (ext4, FAT32, ...)?
Do you execute the installer as root?

[ppitu]

@jsulm I have Etx4 and I run installer with sudo.

And when I try install Qt on my laptop (ubuntu 20.10) I have the same error.

and I run installer with sudo

Why?

[ppitu]

@jsulm I dont have default sudo on my profile so I use sudo to install new things.

@ppitu
That might or might not be relevant. From a shell in the directory where the file is what is the output of these two commands:

ls -l qt-unified-linux-x64-4.5.2-online.run
file qt-unified-linux-x64-4.5.2-online.run

[jsulm]

@ppitu If only one user is going to use Qt there is no need for sudo: run the installer as normal user, Qt will be installed in home folder then.

[ppitu]

@JonB ls -l qt-unified-linux-x64-4.5.2-online.run

@jsulm When I run without sudo i receive permission denied.

i receive permission denied

then set the access rights correctly...

Which shows you have not executed the chmod +x on it, which is why I asked for the ls -l, and hence the error message.....

[ppitu]

@JonB I found my mistake. I execute chmod -x not chmod +x.

Thanks for help :D
