yes sir, i am using windows 10 64-bit,I have even tried uninstalling and reinstalling the software quiet a few times, i don’t know if this helps but any calculation which takes less than 5 sec doesn’t show any error, but the point it crosses 5 sec mark the system shutsdown, also i already sent one mail regarding this issue to support@optiwave.com but i didn’t get any response.
Regards,
Avril
