Hi I just wanted to submit my experiens in installing autocad architecture on this AOA 150-Bb of mine. I first tried to install the program directly, but did not get it to work. Here is how I got Architectural to work. 1. Hooked on an externa screen. 2. Installed architectural. It runs really good and Im really happy with this. If you have any questions you are welcome to ask me. /KimmoK
