This patch corrects the sort Order on the media table to use DiskId rather
than LastSequence in ready_media_for_file().
Currently the installer is querying in order by LastSequence. According to
MSDN the sort order should be DiskId. Theoretically LastSequence should work
as a sort order unless you hit an exception where the LastSequence is 0 and
not the first entry in the media table, such as in a higher disk id numbered
media and is supposed to be skipped as the installer checks to see if the
sequence is greater than the last lastsequence and greater than zero for the
first entry in the media table. The installer will currently crash when this
If the installer works the way it should, it should read the first entry in
the media table by the DiskId sort order. Then when it hits an entry with
zero as the last sequence in a higher numbered DiskId it should skip it.
Determines the sort order for the table. This number must be equal to or
greater than 1.
File sequence number for the last file for this media. The numbers in
the LastSequence column specify which of the files in the File table are
found on a particular source disk. Each source disk contains all files with
sequence numbers (as shown in the Sequence column of the File table) less
than or equal to the value in the LastSequence column, and greater than the
LastSequence value of the previous disk (or greater than 0, for the first
entry in the Media table).
