How to build a project in TFS 2015?

Question

Team Foundation Server

Moving from TFS 2010 to 2015, put 2015 on a test server, and I'm trying to set up a build. The agent is on Windows Server 2008 R2
Regardless of what is selected for the build - MSbuild or Visual Studio build, I get an error

Не удалось загрузить обработчик PowerShell задач MSBuild с версией 1.0.11.

or

Не удалось загрузить обработчик PowerShell задач VSBuild с версией 1.0.11.

Google said that the server with the agent needs PowerShell version 3.0 and higher, but 3.0 was already there. Upgrading to 4.0 and 5.0 did not help.
What could be the problem?
