I've never seen such message in 4.0.0. Can this be the cause of the problem?

Using MS Web Expess and SQL
I get the same error 'Portal failed to insall'
So poking around the code, I found this error:
\Install\Install.aspx.vb
  Private Sub AddPortal()
    tries to open the file "\Install\Portal\Portals.resources"  that is not there.

I did find this file in "\Portals\_defaults" though.

I will try to find another group to post this error in so we can get it fixed and move on.

Any luck?  I encountered this when installing a second DNN instance, but using a different objectQualifier.  The install fails with:  Error: The INSERT statement conflicted with the FOREIGN KEY constraint "FK_dn2_TabPermission_dn2_Permission". The conflict occurred in database "tronix", table "dbo.dn2_Permission", column 'PermissionID'. The statement has been terminated.

Where dn2 is my objectQualifier in the web.config file.
