Problems after upgrading to OS X Yosemite? Try these steps
To install, find the downloaded file in your Downloads folder or on your Desktop and double-click on the downloaded file. This should open a Finder window that contains the NeoOffice installer. Double-click on the NeoOffice installer and the NeoOffice installer should start.
By default, the installer will create an application called NeoOffice in the Applications folder.
However, if you already installed NeoOffice 3.x in the Applications folder, the installer will create an application called NeoOffice in the Applications / NeoOffice folder as shown in the screen snapshot to the right.
To uninstall, just drag the NeoOffice application from the Finder into the Mac OS X trash can.
