I'm new to DNN and am trying to install for the first time. I've followed the directions in the install file and have all working on the "http://localhost/DotNetNuke/Install/InstallWizard.aspx" page, up to the Configure Database page. I get the following error. Any ideas? (Thanks in advance) (DNN 4.9.4, MSSQL 2008 Express Edition) Connection Error(s): Index #: 0 Source: .Net SqlClient Data Provider Class: 16 Number: 5120 Message: Unable to open the physical file "C:\DotNetNuke\App_Data\DotNetNuke.mdf". Operating system error 32: "32(failed to retrieve text for this error. Reason: 1815)". Index #: 1 Source: .Net SqlClient Data Provider Class: 14 Number: 15350 Message: An attempt to attach an auto-named database for file C:\DotNetNuke\App_Data\DotNetNuke.mdf failed. A database with the same name exists, or specified file cannot be opened, or it is located on UNC share.

Make sure to grant full file system permissions to local ASP.Net user ("Network Service" by default) for the installation directory and all subfolders.

Do not touch /app_data/database.mdf with a database management tool.
