What are SteamInstall.msi Error Messages?


General SteamInstall.msi Runtime Errors

Download SteamInstall.msi Files (Malware-Tested 100% Clean)


CAUTION : We strongly advise against downloading and copying SteamInstall.msi to your appropriate Windows system directory. Valve typically does not release Steam MSI files for download because they are bundled together inside of a software installer. The installer's task is to ensure that all correct verifications have been made before installing and placing SteamInstall.msi and all other MSI files for Steam. An incorrectly installed MSI file may create system instability and could cause your program or operating system to stop functioning altogether. Proceed with caution.
