I spent most of yesterday and this morning testing various installation scenarios on DNN 5.2.2 and have only managed to make a clean installation fail for 3 basic reasons.  The first is not having the minimum requirements, ASP.NET 3.5 sp1 and SQL 2005 or higher, installed before installing DNN.  The second is a bad connection string in the web config, and only when installing to an instance of SQL 2005 that required a different string configuration  And permissions, both NTFS permissions on the web folders (and having the proper IIS process account) and SQL permissons.

So, if you're getting installation errors, first make sure your server supports both ASP.NET 3.5 with service pack 1 and SQL Server (Express or Standard) 2005 or 2008.  Then make sure that you have the correct configuration in your web.config as your host or admin gives it to you.  Normally this isn't an issue, and you can change these parameters in the installer.  And third, make sure you have the correct IIS process account, paying attention to IIS 7.5's change in the default account name, and that the process account has at least Modify permission on the web folders for DNN.  SQL permissions are rarely an issue in a hosted environment, but if you're adding a DNN database to an existing environment make sure you have the SQL database permissions correct.

Otherwise, the download of the Install version works.  There are some miscellaneous issues, but the install basically works fine.

 Jeff, i thought i had done all this correctly as the install wizard went through with all checks.

Then, when all was said and done, i got this error when the wizard tried to pull up default.aspx

Server Error in '/' Application.

Object reference not set to an instance of an object.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Yes, i have .NET 3.5 sp1 installed. I am using SQLServer 2008, the IIS that comes with Windows 7 Ultimate, and DNN Intall package version 5.2.2

Can you tell me where something went wrong because the Installed didn't say ANYTHING until it tried going into the site. Like i say, i got past setting up Administrator and Portal username/passwords.

Any help would be appreciated...

Was this an upgrade or a fresh install?  Have you cleared the browser cache and recylced the application or site?  Have you checked the event logs for a possible clue?
