Installing Gpg4win from a CD-ROM:

Insert the CD-ROM in the CD-ROM drive of your computer and log in as Administrator. On the screen click on the CD-ROM icon titled 'Gpg4win'. Once the CD-ROM icon opens, click on the installation icon titled 'Gpg4win'.

Installing Gpg4win from the Internet:

Click on [Next].

On the components page you can select which features of GnuPG For Windows you want to install.

This page allows you to set start links for the program. The default setting adds Gpg4win to the start menu only. You can change these settings within Windows at any time.

You have now installed Gpg4win and are ready to use the program.

Prior to starting Gpg4win, we recommend reading Chapter 3 and 4 of the manual "Gpg4win for Advanced Users" (PDF-File). These chapters highlight the ingenious theory behind Gpg4win's ability to encrypt emails in a safe and user-friendly manner.

Of course you do not need to know all the technical details of Gpg4win to be able to use the program. However, since you will use Gpg4win to handle your most sensitive correspondence, it is probably a good idea to understand the theory behind it.
