title: Paths from environmental variables not available in Powershell
body: <p>So I have installed the Team Foundation Server PowerShell Tools, and verified they exist, but the executables (TFPT.exe) do not appear to be available in powershell.</p>
  
  <p>Looking at $env:path (and looking at the path variable through System Properties) I see that the end of the path variable looks like this:
  $env:Path = {other variables};%TFSPowerToolDir%;%BPADir%;.;
  System Properties Enviromental Variables = {other variables};%TFSPowerToolDir%;%BPADir%</p>
  
  <p>When I look at $env:TFSPowerToolDir I get C:\Program Files (x86)\Microsoft Team Foundation Server 2013 Power Tools\, so that seems correct.</p>
  
  <p>But if I try to run tfpt I get the error "The term 'tfpt.exe' is not recognixed as the name of a cmdlet...</p>
  
  <p>If I first do cd $env:TFSPowerToolDir and the run tfpt it works fine. So the environmental variable is correct. But it doesn't seem to get placed in the path.</p>
  
  <p>Any ideas on how to fish this?</p>
