New 5.3.0 still won't work on my two Windows 10 machines with GTX 1070s. No output, regardless of option provided or no option provided. And the lack of debugging info, advice, attention by the dev speaks volumes.

I don't really care anymore. It reports higher hashrates on my Linux machines, but given other people's experiences, I'm suspicious, so I won't use it there.

Amusingly, it does run on Win10 on an old laptop I have that's powering a GTX 970 via external expresscard adapter. But it reports a lower hashrate than dstm so.... there's no point there.
