Qt 5152 Offline Installer !!link!! Info

1. Understanding Qt 5.15.2 & the “Offline Installer” Concept

3.1 Official Qt Download Archive (requires free Qt account)

1. Go to https://download.qt.io/archive/qt/5.15/5.15.2/
2. You’ll see:
   • qt-opensource-windows-x86-5.15.2.exe
   • qt-opensource-linux-x64-5.15.2.run
   • qt-opensource-mac-x64-5.15.2.dmg
3. Login is not required for the archive page (as of 2025), but the installer itself may ask for a Qt account during installation.

Mirror Sites

If the main server is slow, use official mirrors (China: mirrors.tuna.tsinghua.edu.cn/qt/, Germany: ftp.fau.de/qt/). Always ensure the URL path ends with /5.15.2/ and the filename contains opensource.
