Steam Train - Thanks for answering. What you say makes sense. I wondered at the time I uninstalled those programs if it would cause a problem and decided it wouldn't. I took the default install location, which was the C: drive, which is a relatively small SSD by today's standards. I appreciate your answer and won't waste anymore time on that approach. I have the TTX install disks back to 2002 (not sure why I kept them). It sounds like I may as well get rid of them
