Office Enterprise 2007 install fails

[JM]

Office 2007 (with Vista) runs through complete install cycle then finishes
with message:
'Microsoft Office 2007 Enterprise setup has encountered an error' - there is
no error number and no log file; all Office 2007 files are deleted.
I reinstalled Vista; same result
Reinstalled Vista, installed Office 2003 and Upgraded - same result.
(have multiple licenses and CD installed OK on desktop)
Solutions appreciated...
