OpenVPN + Config Windows Installer

This handy NSIS installer script installs both OpenVPN as well as a set of configuration data. It makes it super easy to package and distribute OpenVPN and Configurations to Windows users (like in a corporate environment)

Building OpenVPN Installer

These commands will be executed from the Windows command line, these for example come from our make.bat file.

c:\Program Files\NSIS\makensis.exe \
    /Doutput_exe="vpn-output.exe" \
    /Dclient_cfg="vpn-config" \
    edoceo_openvpn_installer.nsi

Update the comamnd to substitue the desired configuration directory for vpn-config. Also, other files will need to be preset, such as logo icons or images.<
