I tried to find it on the site but could not. Is this program just for private use, or can it be used by a company? Basically I have three people that I have to send confidential stuff out to, and I am trying not to buy 4 PGP licenses. Thanks for any help.
Any of the software modules of Gpg4win
are Free Software. Most of them are
licensed under GNU General Public License.
The definition of Free Software says that
you may use the software for any purpose.
This of course includes commercial use
in any dimension 
The licenses for Free Software “implement” the
Free Software definition.
Awesome. Thank you.
