Frequently asked
Does Crimson Assembly work on Minecraft 1.20.1?
Yes. 1.20.1 is the newest Minecraft version Crimson Assembly declares support for, and the claim comes from the author's own release metadata rather than from a compatibility list somebody maintains by hand.
Which platform or loader does Crimson Assembly support?
Forge. A build for one platform or loader will not necessarily load on another, so this is the first thing to check before the Minecraft version.
Which Java version do I need for Crimson Assembly?
On the newest Minecraft version it supports, Java 17 or newer. The requirement comes from the Minecraft version you run rather than from the modpack itself, so on an older supported Minecraft the answer is that version's Java, not this one.
How do I install Crimson Assembly?
Use a launcher that imports packs, such as Prism Launcher, the Modrinth App or the CurseForge app, and open the pack file with it. The launcher installs the right loader and mods for you; installing a pack's mods by hand is the error-prone way.
Where do I download Crimson Assembly safely?
Start with the author's page on CurseForge, which is where the data here is synced from. MCReference does not host or repackage files. The download link goes to the source recorded for that release; verify the publisher, filename and checksum before running it.
Works on the same versions
Ordered by how much of the recent Minecraft version coverage overlaps, not by popularity.
