title: BuildprocessTemplate running InvokeProcess, getting "File not found"
body: <p>I am trying to run a batch file as part of my build with the <code>InvokeProcess</code> activity. However any combination of <code>FileName</code> and <code>WorkingDirectory</code> makes the build fail with the "File not found: <em>NameOfMyBatchFile.bat</em>" message. Any tips on how to troubleshoot this better?</p>
  
  <p>I have tried putting the entire path in the "FileName" property, and likewise in the "WorkingDirectory" property. The file I am trying to run is under the D:\ disk on my buildserver where the Build Controller and Agents are.</p>
