I'm trying to get an update for the above version of Silverfast for my Epson 1640XL, because our current version keeps crashing. However, the website keeps directing me to version 5.5.2r22, which won't update it, presumably because 5.5.3.r14 is more recent.

Is there a more recent release of 5.5.3 for this scanner? And if so, where can I download it?

Sorry there is no further 5.5.3 release, that version ends there.
The next higher version is the current SilverFast 6 version.
