Ensure your server meets the system requirements. You can download the Invision Community Requirements Checker from the official website to do so.
Download the latest version of the Invision Power Suite here: https://webflake.sx/files/category/169-invision-community-suite-46/
Unzip the download and upload the contents to your server in the directory where you want your Community to run.
Simple visit your website (in some cases you have to manually visit /admin/install in your browser from the directory where you uploaded).
At this point the installer will make sure all your directory permissions are correct and prompt you to correct any issues. You will then be asked for your MySQL database issues and various other information the system may need to proceed.
