[Fixed] Can't update to Supermium 132.0.6834.226 R5, not valid

I'm trying to update Supermium to version R5 via the PA platform but after downloading the update and verifying it I get an error message: "The downloaded copy of Supermium is not valid and can not be installed. This could be due to an incomplete download or other network issue. Please try running the updater again when complete.". I have tried it twice but with the same result. Any idea what's wrong?
