Running Windows XP Home Edition on a Pentium III with 512MB RAM. Downloaded the new 3.6.8 installation files. Only options were Save and Cancel. Saved files, then tried to execute Firefox Setup 3.6.8.exe. Error message is "Firefox Setup 3.6.8.exe is not a valid Win32 application."

It is possible that your anti-virus software is corrupting the downloaded files or otherwise interfering with downloading files by Firefox.
You can try to disable the real-time (live) scanning of files in your anti-virus software temporarily to see if that makes downloading work.
Do not forget to re-enable the scanning in your anti-virus software after you are finished with downloading and installing.

See http://kb.mozillazine.org/Unable_to_save_or_download_files (Disable virus scanning in Firefox preferences - Windows)
