Solution?

What's your computer system and Firefox version?

Have you tried to just download the file? Sometimes anti-virus can get in the way.

The Firefox installer uses 7-Zip self-extracting archive technology internally, but usually it's invisible and you wouldn't see any reference to 7-Zip and the setup would just run.

Do you have 7-Zip installed on this system?

Perhaps you might have better luck with the "full" installer?
