This has been dormant for a while, but thought I would post the solution to my issue in case it helps anyone else.   Basically, there is a known incompatibility between AVG Anti-Virus and Meraki.

I noticed it wasn't working recently, so uninstalled and reinstalled the agent but to date, I have not been able to get it running properly again. In addition, I have noticed that other clients (Windows and iOS) in the organisation are not updating the internal IP address correctly. I am beginning to think it is a Legacy issue, but with no support from Cisco, I have no way of telling. ... View more

Thanks for the suggestions. I have tried both of those although I don't get a "Run as Administrator" option when I right-click on the MSI that is downloaded. ... View more
