Just tried the installer, keep getting this error, ran as normal, and right-click run-as-admin, same error. The “open setup log” button also has a bug, it just closes the install dialog.
Had the same problem with Zorin 17. Uninstalled latest Etcher and went back to Etcher version 1.18.11 (dated 2023) and it worked fine. Thanks to whoever made that suggestion.
