Based on the problem as described, by guess is that the problem rests in the Appeon layer *or* is a configuration issue wrt to permissions while running inside the context of a Web Server. I was trying to download the trail but after I submitted the 'survey' the site encountered some sort of error. Now it is stuck where it only offers the mobile as a trail (even when I attempt to download the Web edition).
Anyways, I am also confused as to why the Appeon configuration lists SQLAnywhere/UltraLite as one option because they are in fact different technologies (albeit delivered in the same software package). Certainly, you cannot configure connections to SA and UltraLite using the same driver or same configuration (there are shared connection parms but there are too few of those to generally make a connection to SQL Anywhere generally).
Perhaps someone from Appeon can give this a try - they would be able to check this faster than me as I haveno access or experience with Appeon.
I assume that Patrick's workaround is acceptable?
