Fear not, Leopard users, Apple is still watching out for you. QuickTime 7.7 for Mac OS X 10.5 Leopard closes quite a number of security holes. As is common, we have no sense of how worrying these vulnerabilities really are, but it’s probably worth updating if you use QuickTime in Leopard. And if you’re running Snow Leopard or Lion, move along, there’s nothing to see here. (Free, 68.85 MB)
Open Files with App Switcher
Using the Application Switcher to open files can sometimes be faster than hunting for an Application's window or searching through a jam packed Dock for an Application's icon. First grab your file, press Command-Tab, and then drop the file onto the desired application's icon to open it within that program.

I downloaded from the link you provided. When trying to install, when I got to "Destination" a got a 'block' saying that I need to use the software update.
Okay, so I launched QT 7.6.6 hit the software update and it said I was up-to-date.
Okay, so I App Zapped it. Tried the QT 7.7 installer still at square one.
I keep playing around, but if anyone has any suggestions...mucho appreciato :)
using Mac OS X 10.6.8
http://www.apple.com/quicktime/download/ still downloads the old 7.6.9 dmg. File size matches my existing 7.6.9 file, so it's not just a graphics glitch.
Hopefully, Apple's on top of this.
Matt described it the best: "Apple, whose attitude towards backwards compatibility ranges from somewhat cavalier to downright heartless."
