Hi,

I have two problems and hope someone can help me.

1)I recently upgraded from endnote X4 to endnote X5 and now I could not use endnote in Word. When I click on 'go to endnote ’ or ‘cite citations’ buttons in CWYW, I get the massage stating ‘Could not find a copy of EndNote X4.0.2 to launch.&nbsp;Error code = -10814’.&nbsp;

1. In Word I notice that my endnote file is stated as endnote X4 in spite of &nbsp;only having endnote X5 application in my laptop. Why is this and what can I do to change this?

Thanks for your help.

Regards

Jue
