Note that the hash for the file written to disk is the hash of the whole file, despite being labeled "md5lite". 313772 is, as expected, the md5 of the first 512 bytes.
The upshot of this is that we're not able to use any checksum but the default which, for lots of big MSI files whose content is unlikely to change, is pretty expensive in terms of master CPU and IO.
