To be correctly installed our app requires Internet connection. During internet connection our app will check for updates and downloads necessary files for installation. This step required and cannot be skipped.
How do I fix this issue?
Some firewalls or antivirus solutions are too aggressive and block every connection to the internet. If you have firewall or antivirus enabled - try to disable it for a while. Usually, its a source of problem. If this won't help please contact your system administrator.
If I don't have internet connection or don't want to allow your app to connect to the Internet?
In such case our app will not be able to install required files and will not work. Almost all applications now are internet-dependant.
