Answer 1

In my case under Windows 8 Professional:

TC build agent upgrade failed

1. I checked out BuildAgent\logs\teamcity-agent.log, there was trouble with the "upgrade process".

2. I checked out BuildAgent\logs\upgrade.log, there were more detailed "DEBUG" messages. The problem was "access denied" on shutting down service.

3. I added the user account of the TC server service to "Administrators" to let it stop the agent service.

4. I removed the user account of the TC server service from "Administrators" user group.

5. Restarting both service (TC server + Agent) led finally to have:

   BuildAgent\logs\buildAgent.port
   

   file: the agent was finally connected after successfull.
