Please download iscan-2.14.0-3.tar.gz.  Select any of the models
listed at


to get to a page that lets you download that version.

So it seems that you are running a 32-bit version of the package.  In
that case I suspect that you do not have the 32-bit versions of the
PNG (and JPEG) libraries installed.  You should have libpng-32bit or
some similarly named package installed.  Same for JPEG.

Thanks, but I think that your report will be somewhat confusing.  For
one thing, it's not clear what version of whose package you are using.

You shouldn't have to log on to report anything.  Just confirmed your
observation.  I get the same myself.  I'll forward that to our support
