Trouble with installing package

Hi all,

I am a WinEdt 7.0 user and I am trying to install the package apa6 to the MikTex directory so I can use the package.

However, I receive the follow error message:

MiKTeX Problem Report

Does anyone have any idea how to rectify the Windows API error 87?

Thanks for your help,
