Problem solved for me. It had to
Do with how many active CPU cores were available to
The system. If you have more than 8 or
Possibly 16 (with hyper threading) cores available it won't launch.

Here is a copy of the resolution to the problem
I sent to Ubisoft

"The problem had to do with the number of Active CPU cores in this system. I am playing the game on a workstation with dual Xeon E5-2687W CPUs. Each Xeon E5-2687W has 8 active cores, and with hyperthreading this means the operating system has 32 possible CPU cores to work with. I suspected that the way the game had been threading was causing some contention with the Windows task and thread scheduler and underlying microcode.

By shutting down all but 2 Cores in each CPU that leaves 4 physical cpu cores and 4 virtual ones (because of hyperthreading) and then the game worked.

I really recommend you work on patching the underlying microcode in the DUNIA engine that runs FarCry4 to play better with Windows machines that have HIGH numbers of cores."
