You can download 7zip and open the archive. Then just drag the Clangen file to your designated location; like the desktop or another file of your choice and boom! it's just that easy. Within the Clangen file moved from the archive is Clangen.exe, click that and it should open as normal. If you run
into any issues ask the Discord; there are plenty of people who will be more than happy to help. ^-^

Kinks are still being worked out as far as i'm aware.
(Edit: i mean for me it works fine now, but i had to reload a couple times lol, and it's a little bit behind in terms of updates.)
