title: SourceTree ssh-agent path is wrong
body: <p>I have updated SourceTree to version 1.6.15 and after that some paths where changed/messed up.
  Before the update everything went without any issue.</p>
  
  <p>Now the ssh-agent fails to start, the window closes automatically in a matter of milliseconds.</p>
  
  <p>The logs in the sourcetree (sourcetree.log) show this log when I try to open the ssh-agent:</p>
  
  <pre><code>2015-07-13T09:30:32: Attempt to start ssh-agent.exe process [C:\Program Files (x86)\Git\usr\bin\ssh-agent.exe]
  </code></pre>
  
  <p>I have checked the path of the ssh-agent and it is wrong, it should be:</p>
  
  <pre><code>C:\Program Files (x86)\Git\bin\ssh-agent.exe
  </code></pre>
  
  <p>I had been using SourceTree with the <strong>System Git</strong>.</p>
  
  <p>The only way I had been able to fix the issue was by changing SourceTree options for Git and use the <strong>Embedded Git</strong>.</p>
  
  <p>I want to avoid having two Git environments and use only the System Git. Is there a way to to change the path of the ssh-agent SourceTree tries to open?</p>
  
  <p>If I use git from the command line, everything works fine, so I guess the Paths are all set up correctly.</p>
