  • This is the message that pops up when I attempt to run 'MBSASetup-x64-EN' by clicking on the icon or from cmd 'msiexec -i [file]'. I'm running Windows 7 Home Premium 64-bit.

  • Thank you for posting on the MBSA forums!

    If you're absolutely sure you're on a 64-bit version fo Windows (check START | Computer | Right-click to get 'Properties') then the problem is either a corrupt download or a virus/malware on your machine.  That error only appears in one of those two cases, so see if you can determine which is the root cause and drop us a note back so we can confirm.

    Thank you.
