后，这几乎SqlServer is in script upgrade mode的SqlServer处于脚本升级模式SP3安装
同样的问题，但我希望能找到一个答案，每一个解决方案有没有为我工作。
我安装了SQL Server 2008R2 SP3。该服务包更新后，服务将启动，但这个错误在错误日志
10:53:47.93 spid7s Error: 5041, Severity: 16, State: 1.

This is a serious error condition which might interfere with regular operation and the database will be taken offline. If the error happened during upgrade of the 'master' database, it will prevent the entire SQL Server instance from starting. Examine the previous errorlog entries for errors, take the appropriate corrective actions and re-start the database so that the script upgrade steps run to completion.

这是我的注册表设置在几秒钟内停止：
HKHKEY_LOCAL_MACHINE \ SOFTWARE \微软\微软SQL服务器\ MSSQL10_50.I2008 \ SETUP \ SQLDataRoot
F：\ Program Files文件\ Microsoft SQL Server的\ MSSQL10_50.I2008 \ MSSQL
HKEY_LOCAL_MACHINE \ SOFTWARE \微软\ Microsoft SQL Server的\ MSSQL10_50.I2008 \的MSSQLServer \ DefaultData
K：\ MSSQL.1 \ MSSQL \ DATA \
F：\ Program Files文件\ Microsoft SQL Server的\ MSSQL10_50.I2008 \ MSSQL
，我试图
F：\临gram Files \ Microsoft SQL Server \ MSSQL10_50.I2008 \ MSSQL \ Data
，但是什么都不做。
在与MSDB数据库的文件夹，这些都是权限：
SYSTEM: Full controll
SQLServerMSSSQLUser$<servername>$<instancename>: Full control
Administrators: Full control
我尝试添加的服务帐户的RN中的SQL Server实例，但那不起作用。 另外，硬盘上有足够的空间。 我该怎么办？
