Reading Windows Registry in QT

I want to list all applications that were installed by reading the registry file to remove from HKEY_CURRENT_USER. But it looks like it cannot be done using QSettings, for some security reason (I think).

QSettings maya("HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Uninstall


People suggest using WinAPI to accomplish this (at least on the Window platform)

Can anyone advise me on how to add and use this library please? thank

To get a list of all the sub items under "Delete" in the Windows registry, you need to use a function QSettings::childGroups()

, ie:

QSettings m("HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Uninstall",
QStringList ak = m.childGroups();


This will return a list of all installed applications.


After getting a list of installed applications, you can read the installation information. There are two ways to do this. For example, to read the UinstallPath key for an Autodesk Maya 2014 application:

m.beginGroup("Autodesk Maya 2014");
QString path = m.value("UninstallPath").toString();


or simply:

QString path = m.value("Autodesk Maya 2014/UninstallPath").toString();
