Hello, 

I am getting "Access is denied" error every time I try to generate OAuth2 token using the "OAuthTokenGenerator.exe" program. and I am using Client ID and Secret from "console.developers.google.com -> APIs & Auth -> Credentials.

Any kind of help will be really appreciated.

ok, Found the problem. My Port 8080 was busy, and the Application was crashing. So I debugged the code and changed the Port Number, and its working now.
