I don't personally have much experience with using GnuPG on the
Windows platform, but I can say with reasonable confidence that
--disable-ccid is not a gpg option.  On Unix/Linux, that option is for
scdaemon, a component which is installed with GnuPG 2.0.x and which
manages the smart card interface.  Typically to use that option you
would put "disable-ccid" into your scdaemon.conf file, as scdaemon is
rarely launched by the user directly.

I'm sure someone with gpg4win xperience will be along shortly to be of
more help.
