Dan, It appears that that you are opening the OpenOffice program from within the downloaded dmg file (i.e., from the window described below). That file contains a virtual disk that contains the program and other files. You are supposed to copy the OpenOffice program from that virtual disk to the Applications folder on your computer.
The steps for installing OpenOffice on a Mac are as follows: 1. Download the OpenOffice distribution file Apache_OpenOffice_4.1.7_MacOS_x86-64_install_en-US.dmg. 2. Double click on the icon for the dmg file (i.e., wherever it got downloaded to), which will (a) mount the virtual disk contained in the dmg file, which creates an "OpenOffice" icon on the desktop, and (b) display the virtual disk's contents in a window named "OpenOffice" (which is the "screen" referenced in the instructions that you quoted). 3. *In that "OpenOffice" window*, drag the "OpenOffice.app" icon to the "Applications" icon (also in that window—it is an alias for the actual Applications folder). (You appear to have dragged the "OpenOffice" icon from the desktop to the Applications folder, which is not the same thing—different name and different source location.) 4. Close the "OpenOffice" window. 5. Select (single-click) the "OpenOffice" icon on the desktop, and select File > Eject "OpenOffice". (You could also right click [or hold down Control and left click] on that icon and select Eject "OpenOffice" from the menu that is displayed.) 6. Drag the downloaded dmg file to the Trash (or save it somewhere for [unlikely] future use). Then, to use OpenOffice, double click on its icon in the Applications folder. If you want to avoid having to go to the Applications folder (or the Launcher?) each time you want to use OpenOffice, you can keep its icon in the Dock permanently. I hope this helps, Chuck P.S. For the record, I have not looked at the instructions posted on the OpenOffice website.
