So you said you have FTP access and you can edit php.ini.

If the server has mcrypt installed but not enabled then if you add:

extension=mcrypt.so

then save php.ini and upload, this should work. Note that some servers don't load user's php.ini, instead they are looking for a .user.ini file in root folder.

I would suggest you, if my above answer doesn't help you to contact your hosting provider.

I solved this issue by put in COMMENT the error message validation for mCrypt inside the file

/install/controller/install/step_2.php change inside private function validate()  
//if (!function_exists('mcrypt_encrypt')) {
//  $this->error['warning'] = $this->language->get('error_mcrypt');
//}

and voila

and after install this extension Then, you may want to try this extension:

If you're using a linux system and you have access to the console, you can just activate the mcrypt module in the php.ini.

Type into your console:
```
$ sudo php5enmod mcrypt
```
This will enable the module. If you are using PHP 7 instead of PHP 5 use phpenmod instead.

If you get an error, install the module first with

$ sudo apt-get install php5-mcrypt

or for PHP 7 with

$ sudo apt-get install php7.0-mcrypt

After this you have to restart your webserver. Use this command for apache2
```
$ sudo service apache2 restart
```
or this command for nginx
```
$ sudo service nginx restart
```

If you dont have access to your terminal by any reason, it could be possible to enable it trough the control panel (cPanel, Plesk, ...). In the most cases it's a one-click activation and not really complicated.

Thanks for your reply! I have access to the php.ini file on the FTP is this where I should write this? So sorry but I don't know what a console really is? But I do have access to a controlpanel from my web-hotel provider. — GetGalax, Aug 01 '17 at 19:34

In case you are using apache2 on ubuntu :

First try to enable mcrypt using command:

sudo phpenmod mcrypt

If mcrypt is not installed, install it using below commands for PHP

PHP 5.6 :

sudo apt-get install php5.6-mcrypt

PHP 7.0:

sudo apt-get install php5.6-mcrypt

Enable mcrypt after insatallation and restart apache

sudo phpenmod mcrypt
sudo service apache2 restart

The only solution that always works with me it to use PHP 5 & mySQL 5 (5.x anything) And in the hosting, assign the php version 5 (outdated) to the website, also make sure that the database is mySQL (5.x)

Thanks
