Hi!

I have downloaded DNN Source, unziped the files and generated a virtual folder in ISS,
and changed the web.config file.
I have used the installation manual downloaded from DotNetNuke.com.

When I tries to install DNN, the error: Object reference not set to an instance of an object
when i load the install.aspx in my web browser (http://localhost/DotNetNuke_2/Install/Install.aspx?mode=install).

Can somebody help?

More information:
