    <!-- The following line ensures that DLLs are replaced even if
        their version is the same as before or they dont have versions.
        Microsoft's brain dead installer will otherwise use file dates to
        determine whether to install a file or not. Simply not robust. And
        since we dont install any system files whatsoever, we can never replace
        a system file with an older version. This way the calibre install
        should always result in a consistent set of files being present in the
        installation folder, though of course, with Microsoft there are no
        guarantees of anything. -->
