That is actually the thing you can do.

We try to avoid the registry and the forthcoming version will even allow
to act as a “portable” version thereby entirely ignoring the registry.

The suggested way to detect gpg is by calling "gpgconf", which returns
an easily parsable list telling the file names of the actual binaries.
OR you may call "gpgconf --list-dirs" to get a list with information on
the installation directories.  If a registry key has been used to
redirect the standard locations, gpgconf knows about it.  Thus please
use it.  gpgconf is expected to be in the PATH (as is gpg).

An even better way is to make use of the gpgme dll, which is the
suggested API to gpg.
