title: Error installing ODAC 12c with ODT for Visual Studio due to illegal character in node
body: <p>I'm getting this error while installing ODAC with ODT in my Windows 7 x86 dev box:</p>
  
  <p><a href="https://i.stack.imgur.com/tChLV.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/tChLV.jpg" alt="Error"></a></p>
  
  <p>It reads: <em>One or more node names 'pc_xxxx' contain one or more of the following invalid characters "_"</em></p>
  
  <p>My company network domain and my machine name both have an underscore in their names and that's obviously something I can't control nor ask for modifications.</p>
  
  <p>I tried to install it with the -silent flag and tried to generate a response file with the -record -destinationFile c:\resp.rsp command to no avail because the response file is not generated (cmd window just closes, without showing an error).</p>
  
  <p>Are there any workarounds to this?</p>
