Big Sur Installer issue

I'm trying to install Big Sur on my iMac, but keep getting a "installer damaged. Download and installer new installer." Good idea, except I don't know where, how to do that... Anybody can help, please ?

iMac 27″, macOS 10.15

The macOS installers get downloaded to the "Applications" folder. The Big Sur installer will be name something like "Install macOS Big Sur". Delete this file and empty the Trash. Then try downloading the installer again.
