Yes, there's a script made by Max_Real_QNX a year ago.
http://www.boot-land.net/forums/index.php?showtopic=2599Don't know if it's the most recent version of Java since it is a year old but you can get in contact with the author and maybe he might be interested in updating this script.

Another problem: when I use IE7 in VistaPE to visit basic authentication webpage, an error popup says "The procedure entry points sfc_os.sfcisfileprotected could not be located in the dynamic link library sfc.dll" then IE crashes. Anyone has idea on how resolve it?
Hmm.. This would happen if an ActiveX entry is not correctly registered or you're not using the minimally compatible version that contains the procedure that IE is requesting.
You can check if this file is really present inside your PE windows folder and try registering with from the command line using something like: "regsvr32 sfc.dll"
(http://support.microsoft.com/kb/249873) or try using (and registering) other versions of the same sfc.dll - you can view the DLL version looking on the properties of the file.
Looking on google I find only remarks for programs that intentionally modify this file with older XP versions that allow to bypass security under some contexts.
To ensure that your running windows is not causing this matter, I would suggest installing a Vista OS under Virtual Box and then build your VistaPE from this clean environment - if IE7 works well when built from the emulated OS then you will know for sure why this happens.
I'm not using VistaPE at the moment nor Vista for what it is worth so my help on this matter is very limited, I suggest opening a new topic here on the forum and see if some experienced member can help and shed some light on this matter.
On the other hand - I think the latest firefox 3.x script is quite complete and might also become a good alternative for this issue in case it takes too long to find a solution.
