I am trying to install Endpoint security 6.1.2227.0 using the Remote Administrator 6. On several of the client computers, when installing the software, it fails to activate using the valid license. When I try to activate it directly on the machine by entering the license key that I received, it tells me that the license does not match the product, which is incorrect. Is there some particular reason why this happens on some computers, and on others I have this activation issue? All of them have the agent installed with no issues.
