Fatal error: Uncaught Error: Call to undefined function simplexml

Hello WordPress experts
I am a starter in the wordpress plugin and i am using Type for custom post type.
Trying to run the Types plugin in the PHP7 enviornment and its crashing to whitepage with lot of errors. Tried contacting the paid version support(already have) but for the past one year i can see no development on the php 7 support updates (Hope i don’t miss any updates) .
I am using the latest version and i am getting the following error when the debug on

Fatal error: Uncaught Error: Call to undefined function simplexml_load_file() in plugins/types/library/otgs/installer/includes/installer.class.php:652 Stack trace: #0 plugins/types/library/otgs/installer/includes/installer.class.php(66): WP_Installer->load_repositories_list() #1 plugins/types/library/otgs/installer/includes/installer.class.php(37): WP_Installer->__construct() #2 plugins/types/library/otgs/installer/installer.php(7): WP_Installer::instance() #3 plugins/types/library/otgs/installer/installer.php(11): WP_Installer() #4 plugins/types/library/otgs/installer/loader.php(120): include_once(‘/var/sites/home…’) #5 plugin.php(524): wpml_installer_instance_delegator(”) #6 /wp-settings.php(395): do_action(‘after_setup_the…’) #7 /wp-config.php(73): requi in plugins/types/library/otgs/installer/includes/installer.class.php on line 652

Is any one from the community success in running this plugin in PHP 7 environment ?,i tried it and performance is great but wp-admin or any Types supported pages wont work.
Hope i have given the enough detail if i missed any kindly let me know.
