Known Issues

For macOS users

  • Apache OpenOffice 4.1.9 may be flagged by the Gatekeeper facility in macOS X. This is a feature to help guard against malware on Mac systems. The Apache OpenOffice disk images are signed by Apache as required by Apple, but Gatekeeper may still be triggered. If that happens, please follow the below steps.
    • For Mac OS X up to 10.11 "El Capitan": There is a procedure laid out at the following link to allow applications not installed from the Mac App store to run. See the Mac support article
    • For Mac OS X 10.12 "Sierra" and up: In Finder, Control-click or right click the icon of the app. Select Open from the top of contextual menu that appears. Click Open in the dialog box. If prompted, enter an administrator name and password. This is needed just the first time you launch Apache OpenOffice.
  • Mac OS X: Due to a known bug in Oracle Java installations of Apache OpenOffice on OSX that do not have the legacy Apple Java 6 installed will not be able to recognize Oracle Java 7, 8. If not able to upgrade to Java 9 then install the legacy version of Apple Java from the following link: Legacy Apple Java 6. This will allow the portions of AOO that require Java to run properly.

For Windows Users

  • Apache OpenOffice 4.1.9 supports Java 8 (32-bit), which is the recommended configuration; but (especially on 64-bit Windows) you might receive warnings about the Java version being defective. In that case, download and install the Microsoft Visual C++ 2010 Redistributable Package.
