I have installed Titanium Studio, build: 3.4.0.201409261227 on a windows 7 computer. I am having trouble installing the Android sdk & NDK I installed them manually but titanium sitl refuses to see them. I followed the instructions in the install trouble shooting section of the documentation, the results of the Diagnostics for Windows are located here.
