When you start Oxygen or run a check with the Acrolinx Integration, Oxygen displays a window with the title FATAL ERROR and a long list of Java errors. Additionally, the Acrolinx toolbar displays inconsistently or is duplicated.
|Acrolinx Integration for Oxygen||All versions.|
|Oxygen XML Editor||Version 14 or later|
This issue can be caused when you’ve installed two instances of Oxygen with two different installation methods. This issue occurs when you manually copy the Acrolinx for Oxygen software files to the Oxygen "Acrolinx Integrations" directory and use the Manage add-ons window to install another version of the Acrolinx Integration from the Acrolinx update site.
Remove both instances of the Acrolinx Integration and reinstall the Acrolinx Integration with one method only.
