Java FX AU is not working with Non Admin UAC ON with Vista

How to reprodcue

1.) Create a non admin user a/c for Vista machine. Set it to UAC enable

2.) Execute "javaws -uninstall", to make sure no pre downloaded jar files exist in the machine.

3.) Install latest respin pit bundle
http://j2se.east/arc/1.6.0_12/pit/2008-12-19.18_06/

4.) Provide the admin password when asked for it.

5.) Please make sure that you can install JRE without any issue. Now open JCP and go to viewer; No pre loaded jar files are shown

I have already created a CR for this 6787810.

6.) But now; I assume i can atleast get these files with FX AU feature. So I launched the jusched

7.) After 5-6 min. kill the jusched and check the FX AU schedule in HKCU Reg loaction.

8.) Set the system date and time accordingly; and launch jusched.exe again

9.) After FX AU schedule is passed; open the JCP and check the FX jar files in Viewer.

Please check the attached jusched logs for more details. I have tried couple of times but this is not working.

Expected Behavior:
It should show downloaded jar file for FX

Actual Behavior:
No files are downloaded
