Rainloop on IIS 8.5 with PHP 7
<p>I try to install Rainloop on IIS 8.5 with PHP 7.</p>

<p>I get a first error: </p>

<pre><code>[202] Data folder permissions error [is_writable]
</code></pre>

<p>I've tried to edit folder rights and added this to web.config :</p>

<pre><code>&lt;configuration&gt;
    &lt;system.webServer&gt;
        &lt;security&gt;
            &lt;requestFiltering&gt;
                &lt;hiddenSegments&gt;
                    &lt;add segment="data"/&gt;
                &lt;/hiddenSegments&gt;
            &lt;/requestFiltering&gt;
        &lt;/security&gt;
    &lt;/system.webServer&gt;
&lt;/configuration&gt;
</code></pre>

<p>How can I fix this problem?</p>
