NAC Agent 4.9.1.5: Script Error: The value of the property 'nacDispatcher' is null or undefined...

This error shows up when attempting posture assessment on one of our patched Windows 7 computers, using Kaspersky Anti-Virus 6.0.4.1424 for Windows Workstations. It persists even if the Kaspersky Firewall is disabled and Windows Firewall is used in its place. I have a screenshot of the error dialog attached.

The timing is interesting in that it coincides with last week's Microsoft patch tuesday releases.

Has anyone else seen this? I hate to exempt a user by their MAC address but if I don't find a resolution  I may be forced to.

It looks like we have the issue resolved for this computer. When installing 4.9.1.5 directly the problem occurs, however when upgrading from 4.9.0.33 to 4.9.1.5 the problem is not replicated. Very odd, and frankly a waste of my morning.
