Dressing SQLServer is a painful thing, many brothers will encounter, teach me the way to share with everyone, hoping to help brothers
If the SQL Server installation fails, first uninstall SQL Server: First delete the "Microsoft SQL Server" folder generated during installation, open the registry: "Start" - "Run" - "Type" regedit ", Delete HKEY_CURRENT_USER / SOFTWARE / Microsoft / Microsoft SQL Server and HKEY_LOCAL_MACHINE / SOFTWARE / Microsoft / Microsoft SQL Server all deleted all, (note that the Microsoft SQL Server folder is removed throughout) and then restart, there should be no problem!
