Windows 10: Error when manually updating the MSE definitions.

Good morning,


When ever I try to update the MSE definitions for x86 system from this web: https://www.microsoft.com/en-us/wdsi/definitions it fails when executing the "mpam-fe.exe" (https://go.microsoft.com/fwlink/?LinkID=121721&arch=x86) with the following error message:

"mpam-fe.exe is not a valid Win32 application"


This is for the following security intelligence update:

The latest security intelligence update is:

• Version: 1.297.1046.0
• Released: 7/14/2019 7:31:22 AM

I've tried it in two different 32 bit Windows systems and it fails with the same message, but it doesn't show any error message when this is executed in 64 bit system, so this surely is due that the 32 bit definitions where made incorrectly for 64 bit systems.


Any clue about it?


Regards.

:)
