'C:Program' not recognized as an internal or external command

Trying to send the code below to the command line, but I get errors. I know there is an issue with backslashes sent to CMD. Any help here on how to send it? Thanks!

string strCmdText="/C C:\\Program Files\\MetaTrader 5\\terminal64.exe /config:C:\\Users\\vguer036\\AppData\\Roaming\\MetaQuotes\\Terminal\\D0E8209F77C8CF37AD8BF550E51FF075\\config\\common.ini";
System.Diagnostics.Process.Start("CMD.exe", strCmdText);

When you use this:

string strCmdText="/C C:\\Program Files\\MetaTrader 5\\terminal64.exe /config:C:\\Users\\vguer036\\AppData\\Roaming\\MetaQuotes\\Terminal\\D0E8209F77C8CF37AD8BF550E51FF075\\config\\common.ini";
System.Diagnostics.Process.Start("CMD.exe", strCmdText);

then you are trying to start the application CMD.exe, which in turn you instruct to execute a particular application. However, because of the spaces, what CMD is trying to execute is the command C:\\Program with parameters Files\\MetaTrader, 5\\terminal64.exe etc. That is where your error message comes from.

One way to solve this is to add extra quotes around the filename (as Dour High Arch commented): 

string strCmdText=@"/C ""C:\Program Files\MetaTrader 5\terminal64.exe"" ""/config:C:\Users\vguer036\AppData\Roaming\MetaQuotes\Terminal\D0E8209F77C8CF37AD8BF550E51FF075\config\common.ini""";

Note the doubled quotes, which are required to use a literal quote inside a verbatim string literal (@"...").

But this way you are still executing one application (CMD.exe) to start another (terminal64.exe). Why not start that terminal64 directly?

System.Diagnostics.Process.Start(
     @"C:\Program Files\MetaTrader 5\terminal64.exe",
     @"/config:C:\Users\vguer036\AppData\Roaming\MetaQuotes\Terminal\D0E8209F77C8CF37AD8BF550E51FF075\config\common.ini");

You should experiment to see whether you need extra quotes around that application name, but I don't think so.
