Path to unblock TSST in Nero7, for scanning?

Does anybody know the path through the registry, where Ahead/Nero7 blocks drives from being able to do the Disc Quality scan with CdDvd Speed? I looked in every possible place I could think of in Ahead/Nero7 & Vista last night, couldn’t find it. It was tough enough finding where Nero7 saved the burn log, why did they have to make that so hard?

Look here:

Thanks steve b, I did actually find that through about my 10th or 12th Google Search & thank you mciahel for posting the info, it worked.
