Start.process does not work with VSIXInstaller.exe arguments C#

Question

I am trying to run the process to uninstall a certain VS Extension with on a quite mode and it seems the arguments won't pass.

string VSIXInstallerPath = (string)Registry.GetValue(@"HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\11.0_Config", "VSIXInstallerLocation", null);
          Process UninstallVSPackage = new Process();
          UninstallVSPackage = Process.Start(VSIXInstallerPath + " " + (@"/u:GUID /quiet"));

And this is the error I get:

The system cannot find the file specified

When I run from Command Prompts it does work.

Answer 1

To execute a command with arguments, you have to use the Process.Start(string fileName, string argument) overload and pass the arguments to the second parameters.

UninstallVSPackage = Process.Start(VSIXInstallerPath, "/u:GUID /quiet");
