New plug-in is not being detected on Vista/ IE7. On the same machine, the same game applets load properly using the regular promoted 6u5-b04

* Tested build: http://analemma.sfbay.sun.com/net/jano1/export1/deployment/kbr/plugin2-testing/jre-6u5-plugin2-windows-i586-p-01_oct_2007.exe

* Tested Configuration: Vista 32-bit (business, ultimate)/ IE 7

It appears that new plug-in is not registered properly on Vista/ IE 7 so can't play the applet.

* Tested games:

1) Yahoo Super Bounce Out applet
http://games.yahoo.com/games/downloads/bo.html
- Click "Play Web Games"
- JPI is not detected by IE 7/Vista and applet can't be loaded.
(see attached screenshot)

2) Radical Aces:
http://java.com/en/games/desktop/radicalaces.jsp
- Click on "TRY IT NOW"
- Follow instruciton to start the online game applet.
- Can't load the applet using new plug-in, but can load using promoted 6u5-b04

3) Any pogo applets.

4) The same can be said for our jdk plugin demo applets
