I would suggest that you run the program/simulator in compatibility mode.
find the main .exe file or shortcut you use to the application, right click it and select Properties
Once the file properties box has loaded, click the Compatibility tab and then tick the box labelled Run this program in compatibility mode for. Now, select the version of Windows that this application was designed to run on (you can use trial and error and see if it runs better under various scenarios). Once you are done, click OK:
Now open the program and try running it.
I am not sure what you mean -- Did you follow my steps on the Windows 10 computer?
