Mac DNG Converter 12.1 does not convert older Sony .ARW from 2011

[chakrii69412318]

The DNG converter did a great job converting .ARW files from Sony A 7iii but gives me a parsing error when attempting to conver older Sony files. I am stumped. Did the new DNG converter drop camera support? How can I get an older version of DNG converter or any other app to try? 

I am running Mac 10.14.5 (Mohave). Thank you.

Which model Sony camera are the files from?

If you can upload a sample (say Dropbox or similar) so other's can examine and test, that be useful.
