This error can occur if the Controller class is declared in the wrong namespace for your Area. Make sure the namespace matches the area registration.

This is an old questions but I really couldn't find the right answer anywhere else. This was my solution:

I have a solution with multiple projects. All projects were in MVC3. I installed Visual Studio 2012 in my machine and it seems that some projects were automatically upgraded to MVC4.

I got this problem "The controller for path '/etc/etc' was not found or does not implement IController" because the project that handled that route was pointin to MVC4.

I had to manually update their references to use MVC3. You can also do that by opening the .csproj file with a text editor. Find the reference to MVC3 and remove this line:

<SpecificVersion>False</SpecificVersion>

This means that MVC can't find a class that implements IController, whether via the default Controller class, or some other mechanism, that is also named Index in the namespace {DefaultNamespace}.Controllers.Login.

Generally speaking, if you structure your MVC application like the default MVC project structure is, you won't have any issues with this type of thing.

However, if you're using the right folder structure and it's saying this then the Index controller you setup isn't inheriting properly.

This answer is of course assuming you're using the basic default routing that's setup when the project is first created from the template.
