Heliohost download won't work in wamp v3.1 64b php 7.1 (no replies)

Hi gurus

I have no problem if i download files & mysql db from Hostgator and run it from wamp.

However if i download from Heliohost.org, running the related 'Virtual Host', it will just cause a download as a file which is actually the index.php of webpage.

I have already disabled the .htaccess which is have extra line of
<IfModule mime_module>
AddType application/x-httpd-ea-php56 .php .php5 .phtml
</IfModule>

Hope to learn why. Thank You
