Thanks for the helpful reminder, Gymnasiast! Last forum I was active in shutdown around 2010.
So someone posted corrupt .ZIP files? Have the files been fixed?
EDIT:
Launcher still complaining 'Error extracting archive'. So if it's corrupt files, they have not been fixed. Is it confirmed that the files are corrupt, or are you speculating?
EDIT:
.ZIP file for latest macOS release extracts OK and the extracted file runs OK, so seems like we're back to the launcher. and nothing from them yet.
