During the installation, the following error message is displayed: Login failed for user "nt authority\anonymous logon"


This error typically occurs when using Windows Authentication and not SQL Authentication during installation. Since your currently logged in user is being used for authentication, and is probably a domain account or in Active Directory, it does not have elevated enough permission to perform the action.


Create or use an existing a SQL Server user account for use with the installation.
