Can't open Audirvana after entering license number

Hello, I am running Windows 10. I downloaded and used the trial version without a problem. However, after purchasing Audirvana and entering the license number, the program has not opened for me. I uninstalled the program and attempted to download it again from, but now I have errors with the download. Any help will be appreciated.

To install and update Audirvana on Windows 10 you need an app called App-Installer, this app is installed by default when you are using Windows 10 1803. If you don’t have it you can install it for free from the Microsoft Store or with this link:
