Cannot install B2TR

[Voltus]

I have Vista RC1 and Office2007 Beta2.
Everytime I run the B2TR installation software, it just showed the UAC menu
once for permission then ran only for about 15 seconds (checked it from task
manager) then it dissapear from the task manager, then nothing happened.
It's just back idle state like nothing happen.
I already let my it ran for about 15 minutes with no avail.
Anybody face the same problem? Any suggestion?

I have 2,5GB free space.
Already tried the Microsoft suggestion for troubleshooting installation B2TR
(clear temp folder, etc.).

Thanks in advance.

When I ran it, the dialog to continue was hidden behind other windows. Are
you sure it's not lurking in the background? What happens if you run just
it, with nothing else running?
