安装tfs 2013时出现错误TF255146

我研究了如何解决这个错误：

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]"

我怎样才能修好它？

我不需要安装sharepoint和reporting service。我搜索了很多来查找和修复这个错误，但是失败了

安装SQL后是否重命名了计算机

我建议从头开始重建服务器。如果您想选择不同的机器名，请确保在安装SQL（或其他任何东西）之前进行选择

然后安装SQL 2012 SP1，然后安装TFS 2013，您应该可以开始了。

您需要安装SQL Server 2012的SP1。TFS 2013不支持没有SP1的SQL Server 2012

是的，我重新命名了机器，非常感谢您的回答…所以我不需要做任何事情来解决这个问题，而不重新安装sql版本？
