<p>I have checked datafolder path </p>

<pre><code> &lt;sc.variable name="dataFolder" value="C:\Path\Data" /&gt;
</code></pre>

<p>and license file settings</p>

<pre><code>  &lt;setting name="LicenseFile" value="$(dataFolder)/license.xml" /&gt;
</code></pre>

<p>also checked permission all is correct but still it is giving error.</p>
