title: error TF255146 in installing tfs 2013
body: <p>I researched about to solve this <strong>errors</strong> :</p>
  
  <pre><code>TF255146: Team Foundation Server requires SQL Server 2012 SP1 (11.00.3000) or greater.  The SQL Server instance SERVER\sql2012 you supplied is version 11.0.2100.60.
  
  TF255507: The security identifier (SID) for the following SQL Server login conflicts with a specified domain or workgroup account: WIN-3QKNH40DUMD\Administrator. The domain or workgroup account is: SERVER\Administrator.  The server selected to host the databases for Team Foundation Server is: SERVER\sql2012. 
  You can resolve this issue by renaming the conflicting login. To do so, open a command prompt on the computer that is running SQL Server and execute the following command:
  sqlcmd -E -S "SERVER\sql2012" -Q "ALTER LOGIN [WIN-3QKNH40DUMD\Administrator] WITH NAME = [SERVER\Administrator]"
