Holy frack I think I got v193 working. Here's what I did:
1. Download all necessary install files. I used only the files that were being served by what I presume to be Steve's website (aurora2. pentarch. org). The applicable archive file versions are: V151Full, V170, V173, V180, V190, V192, V193.
2. Extract each archive into a separate folder.
3. Before copying contents of each sequential patch into the V151 folder, delete any conflicting files in the V151 folder. Repeat this process until you get to V193. Copy contents of each patch into V151 folder after deleting conflicting files in V151 folder.
4. Once all patch files have been copied, run Aurora. exe from the V151 folder and you should now be running V193 of Aurora. At this point you might rename the V151 folder to avoid future confusion about versions.
The game is now working on my windows 10 machine error free thus far. My previously reported V180 error message no longer appears.
Anyway hope this helps someone else get this amazing game running properly. It is worth the effort!
