Error 1720: Problem with Windows Installer Package

I am trying to download The Edge Estimating Software and as soon as it tries to run the download, I get the below error message. I have had this previously installed and uninstalled a while back.

Error message below copied and pasted:

Error 1720. There is a problem with this Windows Installer Package. A script required for this install to complete could not be run. Contact your support personnel or package vendor.

Could this possibly be because I upgraded to Windows 11 when my system's default operating system was Windows 10?
