You will get that message if VoiceAttack does not detect that is being run as an administrator (as Pfeil was saying).
At the end of the day, if VoiceAttack is doing what you need it to do, it is just a log message and can be ignored.
The reason it is there is to stem the *constant* emails and messages regarding VoiceAttack not working, no matter how many times it's been addressed on the forum (either by FAQ or by post message) or written in documentation or written on the web site
So far, it has worked wonders. Might make a switch for it, tho o_O
