I have the same issue on Windows 7 X64 Pro OA SP1 - Dell Precision T3500. I have installed OMCI 8.1.1 x64. I also receive 'Error 1067: The process terminated unexpectedly.' . I am troubleshooting this issue for about 14 days with no luck yet. The BIOS version is A16. Hope finding here a solution, I have 40 more Workstations that are waiting for a solution :).
PS: I also have 2 monitors on each T3500.
Regards,
Andrei
