You should just use the exe. It's simpler, just double click to run, and there is less risk of getting caught if you want to play bard or oryx 3 using exalt mode.

Search "flash player projector", look for adobe's debug downloads page, and scroll down until you see a download link for a projector for your specific operating system.
