CometChat Platinum Nulled 6.9.12

I have a problem. I uplod the cometchat folder in the root directory, but when i go to : https://playevenly.fr/forum/cometchat/install.php   blank Page ! Do you have a solution ?

Don't waste your time.

Doesn't work whatsoever - getting a blank page when going to /cometchat/ and getting an HTTP 500 error when going to /cometchat/install.php

Don't waste your time.
