We are trying to deploy an application (PB 2019 R3 build 2703) using PowerClient. I successfully deployed to a local instance of IIS on Windows 10 and then zipped the two folders that were created in inetpub/wwwroot and gave them to the clients IT team. They put those folders onto their web server in the same location.
When the user tried to launch the application via their browser, they were given the two options -- 'Download the Launcher' and 'Start the Application'. When doing the former the user reported the following error:
"I received this error from Microsoft Defender SmartScreen: CloudAppLauncher_Installer.exe was blocked because it could harm your device."
Adding an exclusion to Windows Defender may not be an option due to strict security policies. Is there anything else that can be done to get around this?
