Dev for Android, Step by Step?

When executing the AndroidWorks 1R1 File, I will get the message:
The selected items:
Nsight Tegra, Visual Studio Edition 3.1.15202.6244

Missing external dependencies may cause the error of installation:

  • Microsoft Visual Studio

So meaning i need this, right? Or can i deselect the Nsight Tegra Package? In the document it doesn’t say it at all, but when taking a look at step 9 you can see that it was installed correctly?? Am i missing something?
