SQL SERVER 2012 cube deployment error

Question

I am a first time SQL server user trying to do the Analysis Services Tutorials. I am on the last part of Lesson 2 where the cube is deployed. Here is my error message. Note: I did have permission issues originally when trying upload AdventureWorksDW2012.
Can anyone help me here?
