Hi,

I just installed the 4.3.4_install package with these steps:

1. Unpacked the install package in the "C:\Inetpub\wwwroot\" folder and renamed the folder "C:\Inetpub\wwwroot\nuke". My Dotnetnuke root folder is now "C:\Inetpub\wwwroot\nuke".

2. Configured the IIS and made a web application and configured the folders to have write access for the web process user.

3. Made a SQL 2005 database named "nuke" on my local SQL2005 instance. Added a SQL user named "nuke" with the password "nuke" and gave it the db_owner rights.

4. Configured the web.config file like this:

  <connectionStrings>
    <!-- Connection String for SQL Server 2000/2005 -->
    <add name="SiteSqlServer" connectionString="Server=(local)\SQL2005;Database=nuke;uid=nuke;pwd=nuke;" providerName="System.Data.SqlClient" />
  </connectionStrings>

5. Opened IE with the http://localhost/nuke address. It started up and installed lots of modules etc... the install went fine. I got a link at the bottom telling me that it was installed succesfully and something like "click here to take me to the webside" (I don't remember the text).

6. When I opened the http://localhost/nuke again I get this error:

 

Server Error in '/nuke' Application.

Any idéas that I could try are very welcome. I am not sure what to do... 

 

Best regards,

Lars-Inge

Larsinge,

I encountered a similar issue. I am no expert at DotNuke, as a matter of fact I am a total newbie.. But what I did and it resolved this issue was to assign the login user account in SQL Express additional rights, in addition to db_owner. I actually added them all, but if you experiment you can find out exactly which one is the needed permission.

Maybe one of the DotNetNuke Gurus can clarify which one...

I just hit the exact same problem. The solution for me was to change web.config to allow DNN to connect as the sa account. I just posted this as a bug, but if it is feasible for you to do this it is an effective workaround.

Thanks,
Adrian
