After installing SQL Server Express 2012 on my Windows 7 machine, when saving changes in `SQL Server Configuration Manager` for TCP/IP protocol, It errors with The specified file is read only. [0x80071779] Update: The issue seemed to resolve itself.

Accepted Answer

I have the same issue with installing sql 2012 Developer on W7 x64 Pro.

I have solved this huge issue by modify manually the Registry database in :

```
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server\MSSQL11.SQL2012\MSSQLServer\SuperSocketNetLib\Tcp]
```
