Hi,
im trying to install a second instance of dotnetnuke (4.3.3) on my local machine and i'm getting the following error;

Configuration Error

Description: An error occurred during the processing of a configuration file required to service this request. Please review the specific error details below and modify your configuration file appropriately.
Parser Error Message: The entry 'SiteSqlServer' has already been added.
Source Error: 

Line 27: 	-->
Line 28: 	<!-- Connection String for SQL Server 2000/2005 -->
Line 29:     <add
Line 30:       name="SiteSqlServer"
Line 31:       connectionString="viewmobile;Database=coralsolutions;uid=dbtestuser;pwd=xxx;"

I have read the posts relating to this problem and i'm almost certain that my web.config settings are correct.  (see below);

  <connectionStrings>
    <!-- Connection String for SQL Server 2005 Express
    <add
      name="SiteSqlServer"
      connectionString="Data Source=.\SQLExpress;Integrated Security=True;User Instance=True;AttachDBFilename=|DataDirectory|Database.mdf;"
      providerName="System.Data.SqlClient" />
    -->
    <!-- Connection String for SQL Server 2000/2005 -->
    <add

      connectionString="viewmobile;Database=coralsolutions;uid=dbtestuser;pwd=xxx;"
      providerName="System.Data.SqlClient" />
  </connectionStrings>
  <appSettings>
    <!-- Connection String for SQL Server 2005 Express - kept for backwards compatability - legacy modules  
    <add key="SiteSqlServer" value="Data Source=.\SQLExpress;Integrated Security=True;User Instance=True;AttachDBFilename=|DataDirectory|Database.mdf;"/>

    <!-- Connection String for SQL Server 2000/2005 - kept for backwards compatability - legacy modules -->
    <add key="SiteSqlServer" value="viewmobile;Database=coralsolutions;uid=dbtestuser;pwd=xxx;"/>
     

I already have DNN 4.3.1 installed and wanted to install 4.3.3 fresh.  I'm not sure if i can actually have 2 instances of DNN running on the same machine pointing to 2 different databases on the same instance of Sql Server.

any help would be appreciated.

the other connection string was commented out.  Just to be sure, i completely removed the SQLexpress connection strings.  Here is my new web.config.  But the error is the same..

  <connectionStrings>
    <!-- Connection String for SQL Server 2000/2005 -->
    <add
      name="SiteSqlServer"
      connectionString="viewmobile;Database=coralsolutions;uid=coralsolutions;pwd=xcoral12345;"
      providerName="System.Data.SqlClient" />
  </connectionStrings>
  <appSettings>
    <add key="SiteSqlServer" value="viewmobile;Database=coralsolutions;uid=coralsolutions;pwd=xcoral12345;"/>
    <add key="InstallTemplate" value="DotNetNuke.install.config" />


Also,
i'n not actually creating a new portal.  I am installing a completely new instance of DNN 4.3.3 on a machine that already has an instance of dnn 4.3.1.

any ideas
cheers
