Hello,

Same here!!!

It's a brand new install with new database.

After a succesful installation I've set up the HOST account, but at the next step when I was about to set up the Portal Admin account I got the 'server error'
I've set customerrors to off in the web config file, to see what the actual error message is:

Server Error in '/dotnetnuke' 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.

Please help!!!

Object reference not set to an instance of an object is a generic error message, which doesn't provide a hint to the real problem.

if you face it during or immediately past the installation, make sure, you have granted full file system permissions to the ASP.Net user (IIS7: user specified for the app pool). try to restart the application (either recycle app pool or edit and save web.config file).

If the error persists, review IIS web site configuration
