I have installed the additional build agent (v6.5.2) and it cannot checkout sources from TFS. The log file of the agent contains the warning:
WARN - impl.vcs.AgentVcsManagerExImpl - Failed to use TFS checkout on agent. Microsoft .NET Framework 2.0 or 4.0 is required. Please make sure Microsoft Team Explorer is installed.
It seems to be a problem, but I have no idea how to fix it, because bot .NET 4.0 (and 2.x and 3.x) and Microsoft Studio Team Explorer 2010 are installed on the PC. Moreover, I just uninstall TeamCity 6.0.2 from the PC, which got sources from TFS without problem.
What do I wrong?
