title: Teamcity10 + .Net 4.6.1 = wrong MSBuild path
body: <p>After installation .Net 4.6.1 on TeamCity BuildAgents machine I have error in buildstep where I have to use MSBuild 2015.</p>
  
  <p>Error say:</p>
  
  <p><code>Unable to find MSBuild at C:\Program Files (x86)\MSBuild\14.0\Bin\MSBuild.exe\MSBuild.exe, please check MSBuild environment variable to target to Microsoft .NET Framework 2.0/3.5/4.0 or Mono installation directory</code></p>
  
  <p>Where I can define again path of MSBuild?
  When I go to <code>Agents &gt;&gt; Agent Parameters &gt;&gt; Environment Variables</code>  I have parameter like that:<br>
  <code>msbuild     C:\Program Files (x86)\MSBuild\14.0\Bin\MSBuild.exe</code></p>
  
  <p>Uninstall .nets (4.5.1,4.5.2,4.6.1) ane MSbuild and MSbuild Tools did not work. 
  Also try setup new agent but at the end I had the same problem. </p>
