You need to read the uVision Getting Started Guide - you can find it in the 'Books' window, or on the 'Help' menu. You should work through the example projects in it - they guide you through the whole process of creating a project, building it, running it in the simulator, and debugging it in the target. This will give you a proper introduction to the tools and how to use them. By working through the manual - rather than just jumping in - you will ensure that you don't miss some small but vital step and end up with an annoying error message...
