Hello
I have a MacBook Pro running OS X 10.7.5 (Lion)
When I open Microsoft Office 2011 and try to open the endnote toolbar (from Endnote X7) I get the following error message:
"Could not launch /Applications/Endnote X7/Endnote X7.app.
Error code = -10827"
Endnote X7 itself works fine - but not when it has to work in Microsoft Office 2011
Any ideas of what to do? 
Hello, Aabroe:
Does that issue happen after restarting your Mac? If so, as a troubleshooting step, does the issue occur if you open only a new, blank Word document?
Hi Gillian
Sorry for the wait.
The problem has now been fixed by simply reinstalling the program. It seems like that that the problem started due to a former reinstalling which was done in the following way:
Installing the dmg from USB.
Before endnote was opened the USB was removed, which seemed to have coursed some problems.
Apparently the error code I posted was not the only error the user had with Endnote X7.
