While 5.15.2 is a "top" choice for maintaining existing software, new projects should ideally look toward Qt 6. However, if your application relies on specific modules that were deprecated in the jump to version 6 (like certain older multimedia or positioning tools), staying with the 5.15.2 installer is the most practical path.
To use the qt-opensource-windows-x86-5.15.2.exe file effectively, follow these steps:
Run the installer and sign in with your Qt account. If you are using the open-source version, ensure you comply with the LGPL or GPL licenses.
