Microsoft SQL Server 2008 R2 software installation

• Double-click setu.exe to install

• Choose to install - a new installation or add functionality to an existing installation now

• In the installation program support rules, there is a detection failure item, which means there is a problem with my installation path. The inspection found that the path file has Chinese characters and the path length is too long.
  

• Simply select Next step in the product key, license terms, and installer support files.

• In setting roles, select SQL Server feature installation
  

• In the function selection section, select all functions and click Next
  

• Simply select Next in the installation rules, instance configuration, and disk space requirements.

• In the server configuration, this error occurs. It turns out that the same account is used for all SQL Server services. Set the account name to NT AUTHORITY\SYSTEM, do not set a password, and click OK.
  

• In the database engine configuration, add the current account as SQL Server administrator
  

• The same is true here in Analysis Services configuration

• During installation
  

• This error suddenly appeared. The reason was that my computer name and user name were the same, which caused the installation to fail. So I changed the user name, uninstalled Microsoft SQL Server 2008 R2, reinstalled, and the problem was solved.
