I'm sorry about the issue. Please press at the same time the 3 keys Ctrl, Alt, Del on your keyboard, then click on Task Manager, then if shown, click on More details at the bottom
, then click on the Details tab
, then look for any item called soffice then end task it
, then install Endnote.(if needed, restart the computer, and try again)
Please reply at the box below to continue troubleshooting. Thank you.
