latest version downloaded but can't run it

I've downloaded the latest version several times-each time it alerts me that the new version is available. It goes to my download mgr as usual and after it finishes, it disappears without a chance to run the new version.

If I'm already fully upgraded then why does it keep asking me if I want to upgrade? OR if I'm not, what is the issue I'm dealing with?

It is possible that your anti-virus software is corrupting the downloaded files or otherwise interfering with downloading files by Firefox.

Try to disable the real-time (live) scanning of files in your anti-virus software temporarily to see if that makes downloading work.

Yeowsers! That is a bit drastic.

Sorry I can't give you a link, but try to download the file yourself.

That is: look for the version you want on this site and download it yourself. Then run it and see what happens.

Oh, be careful. I don't want you to go through what I just went through with my updates from 16 to 17.

Good luck all the same.
