The Gpg4win package is already GPLv3. Gpg4win itself (the buildscripts and 
NSIS files) but as it packages a combination of software which is partly 
licensed under the GPLv3 the GPLv3 applies to the combination.

Not sure about that and what you mean with spawn. If you are distribution 
Gpg4win as part of another software you have to comply with the License 
restrictions of each component of Gpg4win.

E.g. You have to provide the installer scripts and the documentation sources 
(which is in the 5.6mb source package) but also the sources of let's say GnuPG 
because you are also distributing a binary version of GnuPG.

I'm not sure what you would gain though If we would change the Gpg4win 
Installer scripts to GPLv3. They are already v2 or later so you can distribute 
them under the terms of the GPLv3 and thus changing the license would imho 
just add additional Restrictions.

We provide a source installer for this reason. That contains all the necessary 
source packages.

My suggestion would be that you make the source installer and the source 
package available. This doesn't mean that you have to include it in your 
binary installer. See the GPL for details :-)

Regards,
Andre
