I have the AnimationLab Paleette in TurboCad. What I was trying to do was open AnimationLab from the Icon on the desktop. I also tried Right Click and "run as administrator" , but would get the RunTC MFC Application error. PS, I notice that the AL4 user Guide on the CD has "for version 12.1 TurboCad" on the title page. Is the guide going to be updated ?
