Ok… just to see I renamed the file to “obsidian.exe” and ran it (after scanning for viruses), and it installed and ran. It seems the file download link is broken for some reason.
It is still broken - Here we get the message that this topic ihas been solved I hardly think so II think most people would give up . It seems very sloppy program control
As another data point, I just downloaded Obsidian from the download link using Edge on Windows 11, and it downloaded to “Obsidian.1.4.16.exe” in my Downloads folder. It installed normally.
