502: which -a gpg2
/cygdrive/c/Program Files (x86)/GNU/GnuPG/pub/gpg2

jeff_xeon:/cygdrive/u:503: gpg2 --output fred.good --decrypt fred.gpg
gpg: encrypted with 4096-bit RSA key, ID A3791E7DD935A424, created
      "Jeff Deifik <>"
gpg: public key decryption failed: No such device or address
gpg: decryption failed: No secret key

I have uninstalled the standalone version of gnupg2 before I did this.
It seems most likely that the version of gpg2 being invoked is a cygwin
