Laravel Composer Install

I did copy a laravel project from External server to my local server when I tried to type composer install it showed the folowing error

Problem 1 - laravel/framework v5.0.16 requires ext-mcrypt * -> the requested PHP extension mcrypt is missing from your system. - laravel/framework v5.0.16 requires ext-mcrypt * -> the requested PHP extension mcrypt is missing from your system. - Installation request for laravel/framework v5.0.16 -> satisfiable by laravel/framework[v5.0.16].

I have windows 10 system, and it's an old project so I installed the php 5 with xampp

I tried to add extension=php_mcrypt.so but it didn't work

I added a dll file in system32 also but didn't work

and php.ini look like this

[mcrypt]
; For more information about mcrypt settings see http://php.net/mcrypt-module-open
