How to Remove an Instance from SQL Server 2012

  • Hi All,

    I am facing challenges to remove 2012 SQL Server Instances from my Systems. I am using windows 7 and service pack-1. I am going to control panel and then clicking on programs and features and then uninstall Microsoft 2012 and then click on Remove.

    After that I got a message which is below

    "The operating system on this computer does not meet the minimum requirement for SQL server 2012. For Windows 7 or Windows server R2 , Service pack 1 or later is required. "

    I have already Service Pack 1 is installed on my machine. I tired to Install another but it tells me service pack 1 is already installed on your system.

    I have also run the windows update. nothing is working for me. I have BI edition and Enterprise Edition for sql server 2012 Installed on my machine. Does it cause this problem? Then what to do?

    Can any one please help me? I am in a deep trouble.

    It is giving to install another instance But I can not remove the instances.

    Please help!!!

    Install SQL Server 2012 from the Command Prompt

    Setup.exe /Action=Uninstall /FEATURES=SQL,AS,RS,IS,Tools /INSTANCENAME=MSSQLSERVER
