Using Qt Installer

Proxy

Qt installer uses system proxy by default. From Qt Installer version 3.0.3 onwards you can bypass proxy by starting installer with --no-proxy from command line. In Linux hosts, installer does not understand if http_proxy or https_proxy variable is set without http:// or https:// prefix.
Not working:
https_proxy=10.10.10.10:1010
Working:
https_proxy=https://10.10.10.10:1010

From 3.0.5 onwards, when you start installer and encounter error "Network connection not found" in welcome page, you can modify the proxy settings from 'Settings' page. In Online Installer this will work already in all previous versions.

Offline Installer

If you don't have network connection, you can use offline installers. Offline installer will try to connect to internet at startup, but if connection is not found you can still continue installation. Note that if you are using commercial installer, you need to enter license keys manually. Installer does not understand if there is a network connection but not a real internet access, you need to either provide internet access or no network connection at all.
