Test agent 2013: The setup batch file exited with error code 1

Hi. Today I want show you how resolve errors connect with execute batch file in deploy step before
execute tests.

So in my case I have:

1. TFS 2015
2. Test Controller 2013
3. Test Agent 2013
4. Microsoft Test Manager.

 Imagine, that you have task execute tests before execute tests. You write this script and put it to Microsoft test manager in (Advance -> Scripts).
