This has been a frustrating experience.
I run Kaspersky Administration Server 9.0.2804 and Kaspersky Endpoint Security for Windows 188.8.131.526.
Yesterday we received a new laptop, so I deactivated the Kaspersky license on an unused PC to install it on the new laptop. Soon after the laptop was configured, both the laptop and my workstation started reporting a license violation for the Kaspersky software that was installed. We have a license for 40 computers, and 40 licenses were in use at that point. To add to the problem, both the laptop and my workstation would freeze up hard shortly after reporting the license violation. This condition could be avoided by promptly exiting Kaspersky Endpoint Security after logging on to the computer.
Seeing that the issue could be the fact that KES was still installed on 41 computers, I uninstalled it from the PC I had originally deactivated. When this did not alleviate the problems, I uninstalled it from another unused PC. Up until this point, the administration console showed that 40 licenses were in use, including the two problem computers. After uninstalling it from the second PC, it still showed 40 in use.
Also, every time I would deactivate the license on either problem computer it would reactivate shortly thereafter. After reactivating, it would lock up the PC within minutes unless KES was shut down.
Continuing to have problems, I uninstalled KES from the new laptop and from my workstation. Now the administration console showed, correctly, that 37 licenses were in use. I have since reinstalled KES on the laptop, and it now works normally. My workstation, however, continues to display the license warning, and it continues to lock up when KES is running. The administration console shows that 39 of 40 licenses are in use.
My next action will be to uninstall both KES and the admin console from my workstation and proceed to purge the filesystem and registry of anything related to Kaspersky before reinstalling KES :dash1:
