JSFL File API

I want to use the new JSFL file api that comes with the 7.2 updater, but I am having troubles getting it to happen.
I downloaded and installed the 7.2 updater, and supposedly now the FLfile.dll is to be in “C:\Documents and Settings<username>\Local Settings\Application Data\Macromedia\Flash MX 2004<language>\Configuration\External Libraries\FLfile.dll” (running Windows XP) - but it’s not there, there is nothing in that folder at all.

Am I missing a step somewhere, or did the updater not install the files correctly? How can I access this new feature?

Thanks,
C
