You need a non-Express version of Visual Studio (Standard, Professional, or Enterprise for VS2005). You also need either the C# or VB language installed with Visual Studio. NORMA uses these project hosts for code generation.
You should be able to find this information in the Help/About dialog of your Visual Studio install. The edition (Standard, Pro, etc.) will show near the top of the dialog, and the installed languages will be in the package list.
Express editions do not support any third party plugins. This limitation has nothing to do with NORMA.
