Exit Code: 2359302
Code review found the IsInstalled Rule is in order.
Found the environment is having problems with installing updates on the registry level, for the targeted .dll is not being updated when the initial Software Update Cycle runs.
Resolved by uninstalling KB2803821 via Add / Remove Programs, and rerunning the Software Update Cycle for Patch Management.
The update installed and reported IsInstalled=TRUE; proving the install process is in order, but the system experienced an anomaly that caused those .dll's to fail to be updated.
