When trying to install the quickstart in local mode I get the following message

<b>Warning</b>: simplexml_load_file(): I/O warning : failed to load external entity &quot;file:/C:/xamppnew/htdocs/nestfund/plugins/system/TmplHelixUltimate/TmplHelixUltimate.xml&quot; in <b>C:\xamppnew\htdocs\nestfund\libraries\src\Installer\Installer.php</b> on line <b>2080</b><br />
