'm using SQLExpress 2005 and running the app on Windows Vista

I've downloaded the 4.09.02 build.  I then put all the files in my web directoy.  When I run default.aspx I get an error saying "'dbo.GetPortalAliasByPortalID" does not exist.  So, I found the sql install scripts in Provider/Data/ directoy.

When I run the script InstallCommon.sql I get a sql error saying "Cannot grant, deny, or revoke permissions to sa, dbo, entity owner, information_schema, sys, or yourself."Same goes for all the other scripts like InstallRoles, InstallMembership, InstallUsers.

I dont imagine that I should be running these scripts manually.  It seems that when dotnetnuke is started for the first time it will know the database tables and sprocs have not been created and it will run the "wizard" hear about.  Anyone have any idead?  Shouldn't dotnetnuke default.aspx run for the first time and start the wizard?  Thanks much for any help.

it is most likely a permission issue of the user you created for the database. make sure he is member of the database_owner role, having full permission to create and manipulate database objects.
