Won't recognize my secret key

[Phillip Susi]

gpg keeps telling me that I have no secret key.  Even after I deleted
the .gnupg directory and copied the pubring and secring from another
computer where it works, this system keeps saying I have no secret keys.
 Why does it keep throwing out my secret keys?

Working system:

C:\Users\psusi\AppData\Roaming\gnupg>gpg --version
gpg (GnuPG) 2.0.28 (Gpg4win 2.2.5)
C:\Users\psusi\AppData\Roaming\gnupg>gpg -K
C:/Users/psusi/AppData/Roaming/gnupg/secring.gpg
