The following exception could occur with Check_MK version shipping werk #4499 (1.2.8p19, 1.4.0b4):

Traceback (most recent call last): File "cmk-update-agent.py", line 1230, in File "cmk-update-agent.py", line 255, in main_update File "cmk-update-agent.py", line 271, in do_update_as_command File "cmk-update-agent.py", line 319, in do_update_agent File "cmk-update-agent.py", line 939, in update_deployment_state File "cmk-update-agent.py", line 925, in write_state_file WindowsError: [Error 183] Cannot create a file when that file already exists

This issue occured during update and trying to save the new deployment state. It should be enough to apply the update on the Check_MK server and rebuild the agents.
