title: Why do I get: "--grpc_out: protoc-gen-grpc: The system cannot find the path specified." message?
body: <p>I am following this <a href="https://grpc.io/docs/quickstart/csharp.html#using-visual-studio-or-visual-studio-for-mac" rel="noreferrer">C# Quickstart</a> tutorial for gRPC. I have come to <a href="https://grpc.io/docs/quickstart/csharp.html#commands-to-generate-the-grpc-code" rel="noreferrer">this step</a> where I have to use the following command to generate gRPC code:</p>
  <pre><code>%UserProfile%\.nuget\packages\Grpc.Tools.1.15.0\tools\windows_x86\protoc.exe -I../../protos --csharp_out Greeter --grpc_out Greeter ../../protos/helloworld.proto --plugin=protoc-gen-grpc=%UserProfile%\.nuget\packages\packages\Grpc.Tools.1.15.0\tools\windows_x86\grpc_csharp_plugin.exe
  </code></pre>
  <p>It doesn't work and what I get in the terminal after running commands above is this:</p>
  <blockquote>
  <p>--grpc_out: protoc-gen-grpc: The system cannot find the path specified.</p>
  </blockquote>
  <p>I don't know why the system cannot find the path since I have changed the path in the command so that it points to the files which need to be executed.</p>
