If you are logged in as a non-administrator user, you may fail to install the IWA app using the Microsoft Edge browser.
Solution: Go to the installation directory of the IWA Runner (such as C:\Users\%username%\AppData\Local\Appeon\Appeon IWA Runner), right click the CheckNetIsolation.bat file and then select Run as administrator to run this file. After that, try to install the IWA app again.
