I've tried it out. It doesn't seem to be consistent with the standalone exe from the same download, or the latest release.

 Code:
'test.vbs
Set kixtart = CreateObject("KiXtart.Application")
If err.number = 0 Then
   Wscript.Echo kixtart.WKSTA
   Wscript.Echo kixtart.ONWOW64
   Wscript.Echo kixtart.BUILD
   Wscript.Echo kixtart.PRODUCTTYPE
End If

 Code:
;test.kix
? @WKSTA
? @ONWOW64
? @BUILD
? @PRODUCTTYPE
