The program tries to install .NET version 4.5, even if you already have a later version installed. If the setup has any problems with that part, it will retry 2 more times (3 attempts in total). If the third attempt fails, the program reports an error. The error dialog suggests trying later, and states that if the problem persists, please contact (and then ends abruptly). The user has no idea what text was supposed to be after the words “please contact”
If the user attempts to use the Audial’s Support contact, the website states that the user has to sign in to see the page. If the user does not have an account, they have a form to sign-up. After entering the data, filling out the Captcha field, and then clicking on Register Now, the form responds with an error: Unknown API error.
So in short, if the program does not install, you cannot even let them know any details because their website has its own issues.
