title: How to set Wix Property from UI which user can change during installation?
body: <p>I have Wix Code which simply installs a txt file in the given location</p>
  <p>The target location is enclosed in a Property <code>THISONE</code></p>
  <pre><code>&lt;Fragment&gt;
    &lt;Property Id=&quot;THISONE&quot; Value=&quot;C:\MyFolder&quot;/&gt;
    &lt;Directory Id='TARGETDIR' Name='SourceDir'&gt;
      &lt;Directory Id='APPLICATIONFOLDER' ComponentGuidGenerationSeed=&quot;{75266e3e-3781-47e3-ac29-46a2d90548f9}&quot;&gt;
        &lt;Directory Id='MyFolder' Name='MyFolder'/&gt;
      &lt;/Directory&gt;
    &lt;/Directory&gt;
    &lt;SetDirectory Id='APPLICATIONFOLDER' Value='[THISONE]' /&gt;
  &lt;/Fragment&gt;
    
  &lt;Fragment&gt;
    &lt;Component Id=&quot;Component1&quot; Directory=&quot;MyFolder&quot; Win64=&quot;yes&quot;&gt;
      &lt;File Id=&quot;FirstFile.txt&quot;/&gt;
    &lt;/Component&gt;
  &lt;/Fragment&gt;
  </code></pre>
  <p>I want a minimal UI with maybe just a textbox where I can edit the property value so that I can change the target installation file path.</p>
  <p>How can I achieve that ?</p>
  <p>Thanks in Advance</p>
