After we install the SQL2005 database, we need to install the SP4 patch with an error: The workaround for the Windows Installer MSP file cannot be installed
1. Start-Control Panel-Add or Remove Programs, uninstall the Microsoft SQL Server Installer support file, and make sure that there are no remnants of the file.
2. Copy the SQL2005SP4 patch package and change the format of the copied file from the original. exe executable file to a. rar compressed file. (The EXE file is compressed)
3. Open the zip file, view the file, unzip the file "Hotfixsqlsupport\files" in the Directory "SqlSupport.msi", and then double-click Install.
4. Install the EXE program again.
