Exporting STAGING_WRITECOPY=1 used to work as of 1.6.2. I'm using Wine 1.9.24 and this is not working anymore - I'm getting the same errors as the others (Game doesn't launch). COMPHOLIO_WRITECOPY=1 didn't work either.
That's because the patch is still only in staging and Wine staging 1.9.24 never happened. Try with staging 2.0-rc1.
