Also I remember that on Windows 7 I recently had problems with Java installations, for Matlab7.0.
The problem shared by this type of installation is a problem of compatibility of the jdk (IMHO) with Windows 7.
0. Right-click the executable installation and select the voice file properties, and then go to the compatibility section
1. tick the box to use the mode compatibility
2. choose the compatibility with Windows Vista Service Pack 2 (the really-working compatibility option for this kind of things)
3. make sure you launch the executable as an administrator
In the end, installation starts where it didn’t started before (for matlab 7), and starts instantly (instead of waiting tens of minutes ) for JMF.
I hope that this will come in handy in some way.
This ‘trick’ also works for Tomboy notes, typical note-app for linux, also available for windows after installing gtk#
