So my A/V quarantined some files as I was installing my newly purchased 767.  I knew better; I should have disabled it.  I did manage to restore said files and I whitelisted the scripts, including the one to ACE.  I did this recently with my 757 and all is well...no issues.
The a/c loads and flies without any issues.  The 767ACE.exe file shows under my directory, but when I try to open it, nothing happens. 
I uninstalled/reinstalled several times with my A/V turned off, and I even redownloaded the 767 and tried again but no dice.
Any suggestions?  Thank you.
