Qt 5.15.3 is in any case a commercial only available release so if you are missing something there you should contact the Qt Company directly.

Not sure I understand the question. If you need a 64bit version of your app install 64bit Qt and rebuild your app with it.

Yes, you can install 64bit Qt version using Qt Online Installer or the maintenance tool.
