WEB HELPDESK UPGRADE ISSUE FROM 12.7.4 TO 12.7.7 ----The installer cannot be run on this system

Hi my fellow THWACK members,

Hope you are all fine,

I'm currently trying to upgrade my WHD from 12.7.4 to 12.7.7; I download the installer from the customer portal. Unfortunately when I run the installer as admin, I'm getting the error message "The installer cannot be run on this system". Can anyone encounter this before or am I doing the upgrade the wrong way. I join the screenshot below

I am using windows server 2019 standard edition. This server host as well Solarwind platform which is working properly.
