No option to export to media encoder AE CS6

My first Guru lesson here shows how to add comps to the render queue in CS6

When Media Encoder is not in the Ae menu, you need to open Media Encoder (standalone app) and add the comp to it. This is exactly what is shown in the tutorial at about 29 minutes:

Also, for the benefit of future-forum-viewers, don't look in the export section, the command is Composition > Add To Adobe Media Encoder Queue.

The fastest way to create videos using Adobe Media Encoder with After Effects is to use the After Effects render queue to export a losslessly encoded master file (e.g., using the PNG video codec in a QuickTime .mov container file) to a watch folder that Adobe Media Encoder monitors. You can assign encoding presets to a watch folder in Adobe Media Encoder so that it automatically encodes using whichever settings you have specified. One advantage of using this method is that it uses After Effects performance features for rendering (such as GPU acceleration and multiprocessing where applicable) and Adobe Media Encoder performance features for encoding (such as parallel encoding). The disadvantage of using this method is that it occupies the main After Effects application for the entire rendering operation, during which time you can’t use After Effects for anything else.

I can understand wanting to use the Adobe Media Encoder directly though. That would have the advantage of allowing you to continue working in After Effects while the rendering and encoding takes place, since the rendering is performed by a background instance of After Effects. The rendering phase may be slower in some cases, compared with using the After Effects render queue, because the headless version of After Effects rendering in the background does not have access to GPU acceleration and multiprocessing features.

I'm pretty sure that option was added in more recent versions of AE. You should be able to import your AE composition in the Adobe Media Encoder though (pulling it in vs. pushing it).
