MX Installer is corrupt

[lionize]

Received the following error on launch of MX Installer.

"-- FAILED START - The installation media is corrupt. --"

Dual booting MX-21/Windows 11 on Lenovo 64 bit laptop. FWIW here's the entire terminal activity:

"$ sudo minstall
QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime-root'
Installer version: 22.12
<< void MInstall::startup() >>
Detect EFI: 64
Exec #1: uname -m
Exit #1: 0 QProcess::NormalExit
Detect arch: "x86_64"
-- FAILED START - The installation media is corrupt. --"

Is it possible to re-install the installer and if so please point me in the direction of how? If not, can it be repaired or do I need to re-install the entire OS from scratch? Hopefully not, I am trying to create a snapshot of my current setup which took forever to accomplish. If this is a silly question, it's because I'm just learning Linux. Thanks.

You need to download the ISO again. As the installer states it is corrupt, it's not an installer problem it's the media problem -- either the ISO, or there's a problem with the stick you put it on. First thing to check is if the ISO checksum matches. I'm pretty sure there's info about that in the manual.

I'm confused. I thought that after MX Linux was installed and I wanted to back-up my system I could use the installer to create a live usb as a back-up. Isn't it creating the ISO? I am pretty sure I have done this once before but now I'm not sure. It may have been done from my original live usb that I created a second live usb I guess. Could this be my problem? Once the OS is installed on my hard drive the installer no longer can create a live usb? I must be misunderstanding something here. Sorry for the confusion but I just want to create a live snapshot of my current set up on usb. How do I do that so I can have a live usb that I can install my custom setup should something go wrong or just boot it up on any other computer?

MX Snapshot is the program which creates an iso of an installed system. MX Live USB Maker turns the iso into a bootable live usb drive.

Ok thank you. Will give them a try.
