AB Tutor runs fine, then it beeps 3 times and completely shuts down a little while later. 

Cause: 

This is typically caused when a problem occurs with upgrading or when the program (.exe file) is manually copied or moved instead of being installed via the normal MSI setup program. 

Solution: 

You must completely de-install the AB Tutor program and then re-install from the latest downloaded MSI file. You do not need to update or re-install any ABClient programs.
