Q: Windows Defender / SmartScreen blocks the EXE — is it safe?
A: Yes. The warning appears because the executable is unsigned. This project is fully open source — review the source code and build it yourself if unsure.
Q: Which Minecraft version does this support?
A: The installer targets Minecraft Java Edition 1.12.2, the version JennyMod was built for.
Q: Where does the mod get installed?
A: Into %APPDATA%\.minecraft\mods\ by default. You can change the path in the installer UI.
Q: Do I need Java to run the installer EXE?
A: No. The .exe is self-contained. Java is only needed to run Minecraft itself.
