It seems that this is a common occurance with the two programs. I have a user that received a new MacBook Pro with Yosemite (10.10) and this issue seemed to have just started. The Endnote Toolbar is missing as well as the Cannot Fire Event.
I have uninstalled and reinstalled both programs (removed the whole office suite). I did not get the error but the toolbar was missing.
I went into Endnote and found that the Word Add in option was not checked. I checked it and Word started to have the same issues.
Typically, the mentioned “Word could not fire event” error indicates an underlying issue with Microsoft Office’s Visual Basic Editor. To verify this:
1. Quit all Office applications.
2. Use Finder to navigate to the following path:
Macintosh HD : Applications : Microsoft Office 2011 : Office : Startup : Word
3. Clear the mentioned Word folder by moving any add-in files to your Desktop.
4. Open a new Microsoft Word document.
5. In Word, click “Tools>Macro>Visual Basic Editor”.
At this point, there’s no link between EndNote and Microsoft Word. If clicking "Tools>Macro>Visual Basic Editor still results in the appearance of an error message, that’d be confirmation that Microsoft Office is still suffering from an underlying issue. If you’ve tried to remove and reinstall Microsoft Office 2011, you may want to try clearing Office preference files that could be lingering after your reinstallation attempt. You might want to take a look in the following location:
Macintosh HD : Users : [Your user name] : Library : Preferences
You’ll find a number of Office preference files within the Preferences folder, including several com.microsoft.visualbasic.plist / com.microsoft.visual_basic.plist files. You may want to try trashing these office plist files to see if that helps clear up your problematic Visual Basic behavior.
I have a problem with EndNote 7 in Word for Mac 2011 since the last update on EndNote 7.
When I insert a reference using the EndNote Toolbar something like this is inserted in the text {(Bita), 1985 #67}, that is nor considered a reference since if I try to open the Edit & Manage citations it shows a window saying ’ This document does not contain any editable citations."
That is a temporary citation, you need to manually “update citations and bibliography” with the appropriate output style selected in the ribbon, or turn autoformating “on”.
