Installation error with Process Explorer v17.08 ("The downloaded copy of ... is not valid and cannot be installed)

Hello Team,

This is regarding an installation error I encountered with Process Explorer Portable v17.08:
https://portableapps.com/apps/utilities/process-explorer-portable

When running the installer, I get the following pop-up error message:

The downloaded copy of Process Explorer is not valid and cannot be installed. Please try installing again.

While the current portable version is 17.08, it seems the publisher just released a new version v17.09 today. Perhaps this is the cause.

Can you let me know how I can resolve this installation error?
