hello!

i get this error:

Error Installing DotNetNuke

Current Assembly Version: 04.03.02

ERROR: Could not connect to database specified in connectionString for SqlDataProvider

-i use sqlExpress.

-i use the default ewb.config.

-this is my connection string:

 <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

-->

</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

-->

-do i have to use a mixed mode in the sqlExpress?

Try Using this.

<add
      name="SiteSqlServer"
      connectionString"server=<server>;database=<dbname>;user id=<username>;password=<password>;trusted_connection=false;"
      providerName="System.Data.SqlClient" />

<add key="SiteSqlServer" value"server=<server>;database=<dbname>;user id=<username>;password=<password>;trusted_connection=false;"
