A common problem that can occur while using CWYW is that other referencing software may have been installed on the device, such as Zotero or Mendeley.
If you receive the error message "Cannot Edit Range" when attempting to use the EndNote CWYW tools, it is most likely due to the installation of the Mendeley or Zotero plug-in in Word. You should be able to see this in the Word toolbar menu:
To disable the plug-in, select File from the Word document toolbar menu and click on Options. From the Word Options menu, select Add-ins.
Click on the drop-down list next to Manage and select Word Add-ins, then click Go.
De-select the add-in you want to disable, in the example below Zotero, and then click OK.
The unwanted plug-in should disappear from the Word toolbar menu.
If problems using the EndNote CWYW function persist it may be necessary to uninstall other referencing software plug-ins to see if that resolves the issue.
