I recently downloaded several tutorials but am unable to open them. Each time I try a message appears asking if I want the program to make changes to the computer. I click yes and another message pops up. It says welcome to the tutorial setup wizard and asks me to click next. That takes me to the license agreement. I click agree and the next pop up says choose components. There is a blank box, with no component list, and below "install" is highlighted. I click install and the last pop up says that I have successfully installed the tutorial on my computer and to click finish to close the wizard. The tutorial does not start and doesn't give a hint to where it is going. I can't find any where in my PC. I suspect 1) that there is a compatibility issue, 2) there is operator error, 3) they did not download at all. I am using windows 8. Any help would be greatly appreciated because number 2 is very likely the problem.
