I am receiving the error below.  I am attempting to install 4.8.4 Source Package on Server 2003, IIS6, VS2008, SQL Server 2005.  Has anyone seen this problem?  Some of my web.config settings:

I'm having trouble with the install too, but I'm sure it's me.  To the point, my reading of the install documents led me to believe the \website folder had a fully functional build of DNN that also had the source code included.

If I do have the build the app before installing that would explain some of the issues I'm having.

I use the source version usually as well, and there is no need to compile it before use.  However I do not recall seeing that particular error message before, so I cant shed any light on it sorry.  But I can definately say you do not need to compile the source to use it.
