Quotation with process.start. mipony.exe not getting parameter

Quotation with process.start. mipony.exe not getting parameter

I want to launch:
"path"+Mipony.exe /download:linkurl
from my c# app
I know there are several threads with these but I couldn't get it to work
perfectly in my case after reading a lot of them.
In my best attempt mipony is launched but is not getting the parameter
correctly.
Code is using System.Diagnostics.Process.Start
I really tried lot of combinations of \", \"\", \"\"\", @"""" and alike...
also using startInfo.Arguments way.
Also tried launching via cmd like: System.Diagnostics.Process.Start("cmd
/k " + path);
But can't get mipony to receive the parameter. Suggestions?
