I used Fiddler 2, since initially all I wanted to find was the URL with the manifest.
I may give
CooJah a try, later.
What's kk18_9v.exe (6.3Mb), and why did IE9 have 4 instances of it lined up to be downloaded (IE9 has a built-in downloader, with resume and user intervention)? That was an alarming side-effect of downloading Coojah, plus the separate couple of Chinese-language popups.
Coojah: Maybe I should have downloaded the (smaller) ZIP file instead of the full installer (which is 8.7Mb)?
