I seemed to have some problems getting the demo awareim.app installed properly on Mac OS X (10.4.5). It created a folder titled "Contents" in the "Application" directory, which was designated. However, instead of creating an "awareim.app" folder and putting this "Contents" folder in it, it put the "Contents" folder directly in "Applications".
It was relatively easy to fix, but the more timid may be unable to give the demo version a test. I don't know if the production version download suffers from the same phenom.
