 Thanks to all. I have sold the problem. Here are my steps:

1. Download SQLServer2008SP3-KB2546945-x86-ENU.exe from

2.Extract the service pack by running the following command:
                   SQLServer2008SP3-KB2546945-x86-ENU.exe  /x:C:\SP3

3.Run the following file to install the setup support files:
   As  I had no any sql server on my computer to update (I have deleted it before incorrectly)  so there is no any  sql server component to update and I canctled installation
4. After that I renamed setup.exe in setup MS SQL Server 2008 SE directory and copy there C:\SP3\setup.exe file

5 Double click on setup.exe file  I just copied and MS SQL Installation Center stared
   The installation was fine.
You may have to manually uninstall SQL Server.  Please take a look at the following link for more instructions.

I did how they wrote at but the problem is not solved. It seems like the setup.exe can not find and start some file. I manually deleted C:\Program Files\Microsoft SQL Server folder before. So I had to copy this folder from another computer to implement their method at But it doesn't help
First completely cleanup the old SQL instance, try using a program like registry mechanic to scan and clean the SQL related files.


use Registrar Registry Manager from Take ownership of the keys, give the keys MACHINENAME\Administrators Full Control and delete from child keys to the parent.
