Dean,
Thank you for all the help. Unfortunately I had done all of those things, but still to no avail. I even tried all of them again(several times) after your posts, and still nothing. Just before I was about to throw the whole system out into my dumpster I decided to try something. Why I hadn't thought of this before is not clear. I simply took my old hardrive, installed it into my new computer, burned a copy of the aclt.exe from the old drive, then inserted it into the new installation on the new computer. Would you believe that it works like a champ?? I have not put it through the paces yet, but startup is quick with no glitches and it seems to let me perform simple tasks with no meltdown. Unbelievable!?!? I am still in a quandary as to why the installation would never place that certain file into the AC 2000i system folder, but all's well that ends well. If I can help anyone else with this seemingly widespread problem, please let me know. I will make it a habit to check back here from time to time. Thanks to this entire message board!!!
Brian
