Hello,
Check error log of your web server for indicate errors. Usually it can happen if small time limit or memory limit were set in PHP settings. You can try the following solution:
1. Upload component to your server by FTP and unzip. Usually hosting panels like cPanel provide this possibility.
2. Install
PHP Settings plugin and enable it. It increases time limit and memory limit by default.
3. Open Joomla! installation page on the component backend and choose 'Install from directory' section for installation.
Or you can provide temporary access to your Joomla! backend by email(
info@ari-soft.com) that we can investigate this issue.
