I would recommend upgrading.  GnuPG currently comes in two 'flavors': the
1.4.x track, and the 2.0.x track.  Speaking very broadly, 1.4.x is better
for servers, while 2.0.x is more suited for desktop deployments.  Which one
you choose doesn't really matter so much, so long as you upgrade to either
1.4.11 or 2.0.17.  :)

Version 1.2.2 is *old* -- like eight years old.  It doesn't track the
latest changes to the OpenPGP standard, and many bugfixes have come and
gone since then.

Gpg4win may be in version 2.1, but the version of GnuPG shipped with it is
2.0.17 (I believe).

Existing key files and so forth may be migrated to a 2.x installation
quite easily.
