Installation issue at the last hurdle!

Hi
Help again!
I now have xertetoolikit in hdocs xampp drive. When I go to local host and try to login in to install it tells me that all's well. Then when I click on install:
System Requirements

Xerte Online Toolkits has the following system requirements:

A Web server running PHP version 5.2 or above. Your version of PHP is 7.0.2 - OK
Xerte Online Toolkits was developed on PHP 5.2+, it may work on older versions. It may not.
A MYSQL database -
Your version of PHP does not seem to have MySQL support.

Please see PHP's own guide for more details.

Xampp installs come with MySQL installed. However, some versions of PHP may or may not have MySQL installed by default. If you can find a section headed "MySQL" on the PHP Info page, then you should find that MySQL is installed.

Xerte Online Toolkits was developed on ver 14.12 Distrib 5.05.51a for Win32.
We haven't tested this with other versions, or on other database systems.
Notes

Installation Aborted
I tried to paste --msql[DIR]
at line 6 of the php found in Apache admin php.ini

e.g
PHP attempts to find and load this configuration from a number of locations.
; The following is a summary of its search order:
; 1. SAPI module specific location.
; 2. The PHPRC environment variable. (As of PHP 5.2.0)
; 3. A number of predefined registry keys on Windows (As of PHP 5.2.0)
; 4. Current working directory (except CLI)
; 5. The web server's directory (for SAPI modules), or directory of PHP
; (otherwise in Windows)
; 6. The directory from the --with-config-file-path compile time option, or the
; Windows directory (C:\windows or C:\winnt)
; See the PHP docs for more specific information.
; php.net/configuration.file
following the PHP own's guide
but it has reset itself to - config-file-path as shown above


My msql phpadmin states:

Help

Hello,
Is one way to fix it. Try change line in [your xot directory] / setup/setup_class_library.php

this line:

if (function_exists('mysql_connect')) {

to this line:

if (!function_exists('mysql_connect')) {

save and try again install.
