msiexec.exe is the Windows installer. When precisely do you get the error message (what are you doing, and is it a system message, or a message from some other application), and what is the full message?

Currently there seems to be some program called SONIC UPDATE Manager (which I have no clue as to what that is....)

Look through some of these threads, found by searching for Sonic Update Manager.
