If the Acrolinx Word for Windows sidebar edition plug-in is running, and you try to start the Content Analyzer, you'll get an error message 'Entry Point Not Found' and the Content Analyzer will not start.
To avoid this behavior, close Word if you would like to run the Content Analyzer.
The reason for this is because the Content Analyzer and the Word for Windows plug-in both use Qt libraries and there are conflict issues with the DLLs used. Of course, we're hoping to resolve these conflicts in upcoming updates of either the Content Analyzer or the Word for Windows plug-in.
Update to the Office for Word sidebar edition version 1.2 or later and all of your problems will go away. That new sidebar edition of Acrolinx for Office no longer uses the Qt library so you can use the sidebar with Word simultaneously with the Content Analyzer.
