Download Quorix

Version 1.2.0 for Windows 10 and 11, about 26 MB. It includes everything it needs, so you install nothing else.

How to run it

Extract the zip first. Right-click Quorix-Windows.zip and choose Extract All. Running Quorix.exe from inside the zip window does not work, because the app needs the files next to it.
Open the extracted Quorix folder and double-click Quorix.exe.
If Windows says "Windows protected your PC", that is normal for a new app from a small publisher. Click More info, then Run anyway.
Create an account on the first screen and play. The app connects to the game server by itself, so there is no address to type.

Nothing happens: make sure you extracted the whole zip, then run Quorix.exe from the extracted folder.
It says it can't connect: the server may be off, or your network may block it. Try a different network, such as a phone hotspot.
A school computer blocks it: some schools stop unsigned programs. Ask your teacher or IT whether you may run it.
Pin it for later: right-click Quorix.exe and choose Pin to taskbar (on Windows 11, Show more options first).

Quorix keeps itself up to date: new versions download before the app opens. You can also press Check for updates in Settings.
