Before you install
What this installer is, and what it is not.
It does
- Downloads the modpack, mod loader and Java for the arc you pick
- Keeps all of it updated automatically
- Signs you in through Microsoft
- Installs to your own user folder
It never
- Asks for administrator rights
- Sees or stores your Microsoft password
- Touches anything outside its own folder
- Is distributed anywhere but this page
Code-signed by Microsoft
Signed through Microsoft Azure Trusted Signing, so Windows verifies the publisher on every install. Sign-in is your own Microsoft account, the same login as Minecraft; credentials go to Microsoft, never to us.
If your antivirus complains
Some engines flag the embedded Chromium runtime (MCEF/jcef) that powers the in-game web menu. That is a known false positive, not a detection. Open Settings in the launcher and run Fix Antivirus to clear it.
If SmartScreen appears
"Windows protected your PC" on a fresh release is expected: a newly signed build has not built download reputation with Microsoft yet. Click More info, then Run anyway.

PowerShell: Get-FileHash .\Arcbound-Setup-1.2.24.exe -Algorithm SHA512.
The Hash it prints should match exactly. Windows also shows the developer's name on
the certificate, which is expected.
Arc One
Jujutsu Kaisen. Forge 1.20.1.
Arc Two
Arcadia, Cobblemon. Fabric 1.21.1.
The same client, one login. Switching worlds is one click - the launcher handles both mod sets for you.
Always current
Updates arrive signed, from arcbound.org only, the moment you open the client. Broken installs repair themselves.
One identity
Your account, cloaks, hats, titles, and Arc Pass travel with you across every world on the network.
Two worlds behind one Play button

What's new in v1.2.24
- ✦ Home is rebuilt as a console. Your world, your stats, the store and the news sit on one screen, so you never scroll to see where you stand.
- ✦ Navigation moved to an icon dock down the left edge, which leaves the top bar for who you are and whether the client is ready.
- ✦ A new opening animation that plays while the launcher loads instead of after it, so the wait is the show rather than an extra delay.
- ✦ The crash reporter no longer blames 'Authentication failed' or 'Java not found' for sessions that actually closed normally.
- ✦ Creator codes now register on install. They had been failing silently.
