I prefer a different procedure:

1. create a new folder in c:\inetpub, e.g. c:\inetpub\dnn
2. unblock downloaded install zip file
3. extract all contained files hierarchically into c:\inetpub\dnn
4. in IIS, create a new website pointing to this folder (for local test site, use "Default App Pool ASP.NET 4 integrated". Use "DNN" as name and host header
5. in Windows file system, grant modify permission for folder "c:\inetpub\dnn" to the ASP.NET account specified in advanced settings of the app pool
6. edit file "hosts" in folder c:\system32\drivers\etc and create an (uncommented) alias for "DNN" (or which host header you chose before)
7. create a blank website and grant dbowner permission to the SQL server login you want to use.
8. Map this login to a database user (in login properties), using database schema "dbo" .
9. browse the site, the install wizard should come up. even if running SQL Express, select full version and specify instance name, database name and login credentials

Yes. Installed and started correctly with nvquicksite.

Thanks!
