In last months there were unallowed unofficial reuploads of Mod Installers. Those reuploads aren't verified by the development team and thus we can't guarantee their harmlessness, so it's highly possible that they can damage your PC. Using those reuploads isn't allowed by the dev team by any way.
Because the reuploader could modify the internal code of Mod Installer and could add dangerous code and even malware.
It's strongly recommended to download Mod Installer from only this website. You can be sure it's safe to use and can't harm your PC.
NEVER download Mod Installer from other sources and mirrors than this website. If somebody sent you the Mod Installer, rather don't use it and download it from this website.
Now be a bit more attentive.
