I am doing a silent mode SQL Server installation by running my code, This is my code:
string fileName, commandLine = "";
fileName = string.Format(@"{0}\SQLServer\sql64\setup.exe", setupFolder);
commandLine = string.Format(@"PCUSOURCE={0}\SQLServer\sql64 /MEDIALAYOUT=Core /CONFIGURATIONFILE={0}\SQLServer\ConfigurationFile64.ini /ACTION=Install", setupFolder);
Process.Start(fileName, commandLine);
It runs fine and every file is extracted from the installer, after that it pops up an error message

As you notice, I added /ACTION in the command line
/ACTION=Install
Also I checked the configuration file and I found it.
Please help me .. this error killing me :(
Thanks in advance
