After having zero problems with installing the install package of dnn 7.1 on windows7pro and IIS 7 I have attempted to load the source package from codeplex and follow the steps to get it to load and it fails with a database error and never gets to install wizard. Visual Studio 2012 loads the solution fine and builds fine but when loading the website it gets a database error. Do I need a initial connection string that is changed manually unlike the install package which allows entering the database info.
