There is only three files, but you only need to edit only one file, which is the "Website.txt".
You need to edit that and put the URL of your files being download. It MUST be in a .ZIP extension as I use the zip.dll only for compression.
The URL must be like this >> http://www.helbreath.online/Client.zip
The URL will be the exact file that is to be download. I have put an error message if the website URL is wrong.
If the website is right, it will download the file, and will notify you when download is complete to close the updater.
Let me know if there is any problems or error. Good Luck.
