If you are using Windows Vista, 7, 8 or 8.1 you need to right click on the setup file and click "Run as Administrator". Then click "Yes".
Otherwise Windows will not allow Breakaway Audio Enhancer to Install or modify Windows Settings.
And if you have any Antivirus softwares running, disable them temporarily.
I don't know much about ASIO driver, but I have installed FL Studio with ASIO drivers. BAE works fine with ASIO driver running, on my PC.
So I don't think ASIO driver is a problem.
