layer0 posted questions about the Incident Generator a couple of weeks ago, they may be able to help you if you send them a message.
Also the Incident Generator is no longer supported as of version 8.2.
Have a look at the Network Security Platform 6.1 IPS Administration Guide, it has more details about this feature.
Also look in your install directory on the manager for the software.

Layer0 got this response from McAfee support regarding the Incident Generator,
"we contacted McAfee and they respond us that Incident Generator is not present in any aspect of NSP and there is no plan to reintroduce it."
