Installing Qt on Windows
This is a step-by-step manual how to easily download and install Qt toolchain for Windows. Please remind that Qt is free and open-source software and you don't need for a paid license: the commercial license is required for a closed-source software.
Download installer
Unfortunately, an official site became tricky to find a download link. So, there are simple rules how to find it:
- Open qt.io - an official site of Qt project.
- Click the "Download. Try. Buy" button (no, you don't need to buy anything, just find a download link).
- Find the "Download for open source users" block:
- Scroll to the down of a page and find the "Download Qt Online installer" button:
- Click the "Download" button. Alternatively you can get an offline installer for your platform:
- After downloading of installer, run it.
Online installer
Offline installer
Offline installer should don't ask you to login. It hasn't difference from an online installer except of a components list.
Important note: If offlnie installer had to ask you to login, close it!
Then, temporarely disconnect an Internet and start installer again. Then hit "Next" and once you'll get the "Welcome to open-source", feel free to enable Internet back.
