title: How to handle configurations while updating the installer using WIX
body: <p>I'm still newbie with Wix and exploring it! I had made a installer &quot;abc.msi&quot; which is working fine. After installing the abc.msi I go to folder and update my configuration file say it &quot;.env&quot; manually with respect to servers. Now when I update the installer and installs the new &quot;abc.msi&quot; the &quot;.env&quot; gets overridden with new values.</p>
  <p>What I'm looking for &quot;.env&quot; shouldn't get removed and updated newly. It should restore the value which I've updated manually plus should get the new values from the installer.</p>
