<!-- The following line ensures that DLLs are replaced even if their version is the same as before. This
is necessary because of the manifest nuking that was part of making calibre isolated. But I think it
is more rigorous anyway. -->

<!-- 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. -->
