The download does not start
Use the actual Download CorzClient.jar link on the download page. A download may appear in your browser’s downloads panel instead of opening a new page. If it is marked as blocked, review the browser’s explanation and the file’s source; do not bypass a security warning just to continue.
The file is hosted on Codeberg. A Codeberg outage, a removed repository or an unavailable release can affect the link independently of this website. The download notification is a separate server request. It reports a button request, not a completed file transfer, and a notification failure should not prevent access to the link.
The launcher reports an incompatible version
Compare the full version numbers, not just their first digits. Minecraft, the mod loader, Java and the mod release can each have separate compatibility requirements. The supplied JAR declares Fabric Loader 0.16.5 or newer, but its metadata does not specify an exact Minecraft or Java version. Ask the publisher for those requirements rather than assuming support for the latest game release.
If the launcher reports a missing dependency, follow the dependency named in the error. Do not install unrelated libraries in the hope that they will resolve an unspecified problem.
The game crashes after adding the mod
- Close the game and preserve the launcher log from the failed attempt.
- Confirm that the same profile launches without the added file.
- Remove duplicate versions of the mod from the affected profile, keeping backups outside its mods directory.
- Test the confirmed loader and mod requirements in a separate instance with no optional mods.
- If that works, add your other modifications back individually. Record the change that causes the problem to return.
Do not delete all your worlds or reinstall the operating system as an initial troubleshooting step. A separate instance and one change at a time provide a clearer test.
The browser showcase changes, but the game does not
The module switches, keybind labels, accent controls and workspace settings on this website are browser demonstrations. They are not connected to your Minecraft process. Configure installed software through the controls supplied by that software. The preview does not confirm that every illustrated module exists in your installed build.
Prepare useful information for support
Record the game version, loader version, Java version, operating system, installed mod filenames and the last change you made. Include the relevant error text and whether a clean profile reproduces the issue. Remove account tokens, access keys, private server addresses and other personal details from logs before sharing them.
