On product purchase you will receive a license key to the software. Login to our website with Discord and provide this key to automatically be invited to our Discord server. Here you will find information such as the Windows executable download and other information.
Installing the executable will automatically install the required version of Java to run Comet.
On first run Comet creates a few necessary files, databases for your information and tasks to be stored, config files, along with saving proxies to a file if you use proxies. The install folder is located in appdata which can be accessed by entering %appdata% as a path.
