Fatal error: Maximum execution time of 900 seconds

Hello

I am new to Dolibarr and attempting a local install for a test/development environment. During install I get the following error:

Fatal error: Maximum execution time of 900 seconds exceeded in C:\xampp\htdocs\dolibarr\htdocs\core\db\mysqli.class.php on line 268

I have increased the max_execution time in php.ini and phpmyadmin conf files. This 900 number is not in any of them! I cannot find the source of this error or anyway around it to install Dolibarr.

Pls. look here:
