That's exactly what I did.  I excluded the ace_767.exe specifically, and I restored it from the quarantine section.  After it still failed, I uninstalled/reinstalled several times with my AV turned completely off. 

Like I said, I did the exact same thing with my CS 757 ACE.exe a few weeks ago and it works just fine.  I read the post from CS regarding the AV and it's files then, so I understand the relationship.  I don't know what is going on with the 767.
