Some installers such as Visual Studio and SQL Server Management Studio (SSMS) are online installer that, when installed, will download binaries from the internet.
These kinds of installers may not work in certain situations (ex. disconnected, user proxies) and therefore it would be good to have a clear indication of this from PMPC.
Bonus points for also listing what URLs/domains the installer reaches out to so that customers can whitelist them if necessary.
