See
https://forum.qt.io/topic/111473/maintenance-tool-error-cannot-open-file-for-writing-no-error/
In summary, a bad BIOS prevents QTemporaryFile from generating
different filenames each run. The Qt Installer encounters name
conflicts and produces a cryptic error message:
Cannot open file "" for writing: No file name specified
Is this worth a post on the Qt Blog? I foresee many frustrated and
confused Ryzen users out there who would benefit from a reminder to
update their BIOS.
