hello,
I think there is the problem with patching. I install IC 6.16.100 ISR11 on Scientific Linux 6.6:
1. I don't patch >>> the program can't start-up because "111" license feature can't check-out.
2. I patch >>> the program start-up and "111" license feature is check-out and then it's crashed.
So it's possibility that Cadence has used new technic to detect the fake license/ patching
