DNN7 requires at least .Net 4.0 framework, Windows 7, IIS 7.0, and SQL 2008.
Take a look at the pages listed on the right for details about what's needed to set up your local DNN development environment.
What will you need to establish your local development environment?
1. SQL database server….. SQL 2008 RC Express is free and robust and will run DNN 7.
2. IIS web server...ver. 7 or higher…. this is a Windows component included with some versions of Windows 7
3. Web files (DNN, in this case) … Community version is free from DNN. Use the Install version (not update or source).
