Quartus II Freezing Issue

Hello I am a college student in which we use Quartus II version 9.1 sp 2 for our labs. During my lab I am able to successfully get to the point of creating a waveform with my inputs and outputs. However, when I need to simulate my waveform to acquire my output waveform my program freezes. It will say that the simulation was successful with no errors when it does this. After a few minutes it will ask me to either close the program or wait for a response. I have tried waiting for it to respond (for a few hours) with no success. Before hand I do have successful compilation and I follow my textbook religiously. The family I'm using is Cyclone II (I've also tried it with Cyclone IV) with the device EP2C35F672C6 which is what is listed in my textbook. Please any help would be appreciated!

    I am also a college student using this for a Computer Science class. My problem is almost identical to the problem reported in this thread and resulted in a 'B' grade in a lab. Everything was successful until I attempted to execute a Simulation task.

    The messages in the message window reported that the simulation was successful but the graphics were missing in the window that should have contained the resulting bar graphs of the time intervals for the individual pins. That window was empty and the software was reported as being non-responsive.

    I also was treated to a continual display of a charming little hour glass where my cursor should have been. Additionally, the Windows task manager reported taht Quartus was chewing up about 25% of my processing power.

    It is too late for the lab..and for this class but I am curious as to the cause of this problem. I did a similar lab during spring semester with total success (and a grade of 100% on the lab).

    Hoping to satisfy my curiosity.

    Me and some of my friend are having that problem as well. After testing on several computers, i realize that the problem only happens if you are using Windows 10 Version 1607 (Anniversary update).

    If i'm correct, downgrading your Windows 10 version back to 1511 may fix this problem. If anyone have any others way to fix it, please let me know.

    Hope this may help.
