The phrase “Security Craft mod fabric 1.20 1” combines a game version and a loader expectation. Those two labels are not enough by themselves. You still need a Security Craft Mod build that explicitly targets that combination.
A loader name is a hard compatibility boundary
Forge, NeoForge and Fabric expose different mod-loading environments. A build for one loader should not be copied into another loader profile merely because the Minecraft version matches.
Verify the release label, not the search snippet
Search snippets can be outdated or generated from third-party pages. Use the version information attached to the actual build you plan to install.
Check dependencies for the same loader
If a build needs companion libraries, those libraries must also support the same Minecraft version and loader. One mismatched dependency can stop the entire profile from loading.
Keep loader profiles separate
Use distinct launcher instances or folders for different loaders. Separate profiles prevent a Fabric experiment from accidentally changing a stable Forge or NeoForge setup.
If no compatible build is listed
Do not force the file to load. Use a supported game/loader combination or wait until a release explicitly identifies your environment.
Next step
When you are ready to install, return to the main Security Craft Mod download section after checking that your game version, loader and intended build match. For broader setup context, compare this guide with the installation setup guide.
