A few days ago I had DotNetNuke installed so that I was able to see the default page with the login-option (among other things) in the browser. But there seemed to be a problem loging in which I tried to solve. Apparently I wasn't using the database correctly.

Now I'm using "Microsoft SQL Server Management Studio Express" on top of IIS7. But the problems kept coming which is why I desided to do a completelly new install of DotNetNuke (I wasn't able to login though that I tried both the login-settings from the install of DotNetNuke and the login-settings from the database in "Microsoft SQL Server Management Studio Express"). So I tried "http://localhost/DotNetNuke/Install/InstallWizard.aspx" and modified the Debug="true" in the config.web. WHen I try to access the InstallWizard.aspx I get a long error. This is the beginning of it:

"

Server Error in '/DotNetNuke' Application.

Are anybody able to provide some help to me? It would be greatly appreciated...

Thank you very much in advance!

Thank you for the reply.

But I still have problems, though.

Where do I EXACTLY check whether "impersonation" is set? I found it several months ago, but I don't remember the specific place. I've been searching in "IIS7 Manager" both on the virtual directory and the application directory, but I can't find anything ?

In the "When setting up DNN use 'SQL Server' database instead of Express" I guess I have to choose "custom" during the install of DNN. And aparently I cannot gain any kind of access to DNN trough any browser right now so I planned to begin a completely new install of DNN in another directory in the "inetpub/root". Does this sound like the correct solution?

I searched the web for a "how-to" on the subject of setting the "impersonalization". All I found was that I should right-click either "websites" or "THE website" and choose "properties". On the next windows the options should appear. But I haven't got any option of choosing "properties" either places so I guess I'm not using "impersonalization". But the way a lot of websites gave me the impression that if I wanted to use "impersonalization" I had to write for instance "name='abc'" or "impersonate='abc'" in the top line of the aspx-page. But that isn't an option in this situation.

I guess I should delete my installation of DNN under IIS and retry an installlation and then be sure to use the wizard-customization?
