Exchange 2013 CU7 Installation crash on Mailbox role: Transport Service!!

Question

Hi
I need some help, very urgent.
I started cu7 Installation, and in the middle the Installation failed:
Error:
The following error was generated when "$error.Clear();
            # Apply XML Transforms to FIPS configuration file if schema changed
            Write-ExchangeSetupLog -Info "Applying XML Transforms to FIPS configuration";
            $FipsBinPath = [System.IO.Path]::Combine($RoleInstallPath, "FIP-FS\bin");
            [Reflection.Assembly]::LoadFile([System.IO.Path]::Combine($FipsBinPath, "FSCConfigurationServerInterfaces.dll"));
            [Reflection.Assembly]::LoadFile([System.IO.Path]::Combine($FipsBinPath, "FSCConfigSupport.dll"));
            $configServer = New-Object Microsoft.FSC.Configuration.ConfigManagerClass;
            if(! $configServer)
              Write-ExchangeSetupLog -Error "Configuration Server object could not be created.";
            else
              try
                $configServer.Upgrade();
                Write-ExchangeSetupLog -Info "Configuration.xml was upgraded successfully";
              catch
                Write-ExchangeSetupLog -Error "Upgrade of Configuration.xml was unsuccessfull, $_";
              # Stop the process if it is still running
              # We silently continue because if process has already exited, Stop-Process will throw error
              # Error is non-terminating and so can be suppressed
              Stop-Process -processname FSCConfigurationServer -Force -ErrorAction SilentlyContinue;
          " was run: "System.Exception: Upgrade of Configuration.xml was unsuccessfull, Exception calling "Upgrade" with "0" argument(s): "Root element is missing."

Hi,
If it is unable to start Transport service, please try the following method to solve this issue.
Go to “C:\Program Files\Microsoft\Exchange Server\V15\FIP-FS\Data”
Deleted the file "Configuration.xml" and renamed "Configuration.xml.back" to Configuration.xml.
Then try to re-install Exchange Mailbox Server.
Note: remember to back up the file "Configuration.xml" and "Configuration.xml.back"
Best Regards.
