Before you try to install the Dev Kit, you need to have installed the System Requirements for development.
- Download the source code from the source code tab or use "svn checkout https://IL2CPU.svn.codeplex.com/svn"
- If you downloaded the source code from the source code tab, extract it
- Run install.bat (twice sometimes) as an administrator in /Build/VSIP/
- The batch file will install the dev kit and open visual studio so you can look at the cosmos source code
