There is no separate startup script for version 2. The entire app IS an executable script. I have version 1.0 and 2.0 both in my Applications folder and both run fine. To install copy the dmg to your desktop and double click to mount. Drag the OO icon to your applications folder. Drag the icon from the app folder to your dock. Click to start and WAIT. OO opens a very large swap file, which takes some time.

I have a 1.25 GHz G4 emac with 1 GB ram. It takes about 10 seconds for the script to call X11 and another 5 seconds to begin OO. The first time you run it you must agree to the eula and give it your name. Registration is not required.
