mscoree.dll error message

I upgraded to ACT 2011 from 2010.  The Act Outlook Add-in will not load.  Below is the error message I get:



Not loaded.  Certificate of signed and load at startup COM Add-in is not in trusted source list.



Please let me know how I can repair or fix this.  Thanx.

Hi there,


Could you please provide a little more information regarding the issue you are having.


What version of office are you using?

Also what is the full version of Act! are you using?(Help > About Act!)

What version of windows do you have on this pc? Also is it a 32 bit or 64 bit version?
