I’m having trouble with a software component shipped with ArcaOS but which I installed on another operating system. Do you support that?

In a word, no.

Software and drivers included with ArcaOS and not distributed separately (either freely available from Arca Noae or provided as part of a non-ArcaOS subscription) are not licensed for use on, supported when installed on, nor have they been tested on other operating systems. In short, once you break the terms of the ArcaOS licensing agreement, you are on your own.

An excellent example of this is Arca Noae SNAP included with ArcaOS. This is not a free upgrade to SciTech SNAP/se installed with eComStation, nor is it an upgrade for SciTech SNAP Professional. While Arca Noae SNAP as included with ArcaOS has been updated, it has only been tested with ArcaOS, and is only licensed for use with ArcaOS. Installing Arca Noae SNAP from the ArcaOS installation media on any non-ArcaOS system is a direct violation of the ArcaOS licensing agreement, and Arca Noae will not provide any technical support for such installations, even when the ArcaOS license itself was legally obtained and when the ArcaOS license is not in use (ArcaOS itself has not been installed).
