I have just re-installed the tune-up 2006,from the link I provided you and Used the same key. I will se if I also get the same error as you do, If I do I will find the crack. If not the, I have the installation software that you can have. Mean while you can see if you can find the crack here: http://mscracks.com/search.php?q=tuneup&page=2 But open the downloaded crack file in your test PC if you have one, or in the Virtual PC or at your own risk. Will return to you later with the answer.
