Exporting subkeys impossible on Windows GPG

I followed this answer to have a different password for signing subkey than for master key. The instruction suggests to list the keys from my pubring:

>gpg --list-keys
C:/Users/OEM/AppData/Roaming/gnupg/pubring.gpg
----------------------------------------------
pub 4096R/3B8606BB 2017-07-23
uid [ultimate] Maciej Gawinecki <>
sub 4096R/DCBA68E6 2017-07-23 [expires: 2037-07-18]

And then to export export only a signing key. However, my GPG installation on Windows fails here:

gpg --export-secret-subkeys 0xDCBA68E6! > subkeys.pgp
gpg: WARNING: nothing exported

What am I doing wrong?

try: find the KeyID of the subkey:

gpg --interactive --edit-key [fingerprint]

ctr+C <- to exit from the edit key session, i don't know...

then,

gpg -a -o [filename.asc] --export-secret-subkeys [KeyID]
