Hello, I'm a University student, I downloaded the free version for use in the classroom, and while the process was smooth, when it was time to input the licence number already given in the instructions pdf, it wouldn't allow me too, and there were several other in the class with the same problem. without it, we can't open the program, and can't do the assignments. What can we do?
I have moved this to the Academic Community to ensure it is seen by the right folks who can help you.
did you run setup.exe as Administrator ?
If it does not help, create new clean Administrator account in Windows, login as this new user and run setup.exe
