= Rolling out Windows OpenVPN clients =
This guide is based on [[http://openvpn.se/files/howto/openvpn-howto_roll_your_own_installation_package-Rev1.1.html|HowTo Roll Your Own OpenVPN Windows Installation Package]].

The Windows build machine must have [[http://nsis.sourceforge.net/Download|The Nullsoft Scriptable Install System]] installed. Next obtain the [[http://www.openvpn.se/files/install_packages_source/|installation source package]]. If problems persist with differing versions of OpenVPN on the client and server try using the same version as the server on the client. E.g. Server version: 2.0.7, download [[http://www.openvpn.se/files/install_packages_source/openvpn_install_source-2.0.7-gui-1.0.3.zip|OpenVPN GUI install source 2.0.7]]. In theory all 2.0.x releases should be compatible with each other.

Extract openvpn_install_source-2.0.7-gui-1.0.3.zip and open the newly created folder.

In the {{{openvpn\config}}} folder place the generated {{{key}}} and {{{config.ovpn}}} files from the [[OpenVPN]] document.

Return back to the root of the {{{openvpn_install_source}}} folder and open {{{openvpn-gui.nsi}}} in an editor.

{{{
# Include your custom config file(s) here.
  SetOutPath "$INSTDIR\config"
  File "${HOME}\config\key"			# Add this line
  File "${HOME}\config\config.ovpn"		# Add this line
}}}

Finally the {{{openvpn-gui.nsi}}} file needs to compile and build an installable executable. Right click on {{{openvpn-gui.nsi}}} and select Compile NSIS Script.

If successful a file similarly named to {{{openvpn-2.0.7-gui-1.0.3-install.exe}}} will be generated. For easier management, include the client side IP address in the file name. E.g. {{{openvpn-2.0.7-gui-1.0.3-install-10.3.0.2.exe}}}.
