Problem:
The client receives a "Failed to add item" error when attempting to connect to KEPServerEX and add items that are managed by the Fanuc Focas drivers.

Solution:
These drivers have external dependencies that need to be obtained from the Fanuc distributor or by calling 1-888-FANUC-US (1-888-326-8287). These libraries should be located in the System32 folder (or in SysWOW64 on a 64-bit operating system) and are named "FWLIB32.DLL" and "FWLIBE1.DLL".
