Cannot Edit Bibliography "Document not open"

Hi, everytime I opened endnote and try to format my cwyw bibliography, I always get a Parameter is incorrect error with the cwyw.dll always in a temp folder. I have to then always manually navigate to the common folders to add the .dll back. Is there any way to fix this so that when I open word each time, it can automatically load the .dll from my common folders instead of to the TEMP folder so that I dont have to manually select it everytime?

Thx
