[Users] New Windows Users: S/MIME

[Luke Robison]

Andrej, Paul,

Thanks for the quick responses, I'm sure I'm being dense, but I'm still
stuck.  See below:

It looks like it is finding my GnuPG that I installed:

 Under Configuration->Preferences for current account->Account->Privacy the
Default Privacy system is set to PGP MIME, and in fact I have even tried
removing the PGP Inline plugin, so my only options or PGP MIME or None.  I
can also check the setting in the Compose window, and it is set to PGP MIME.

Despite all that, I still see "sgpgme_setup_signers: OpenPGP protocol".
And the "secret key not found" error.  Does this mean I'm not using PGP
MIME?

Should I be concerned about the "no GPG_AGENT_INFO" note in the log?
