Otherwise, use `RegDeleteKeyW` instead, on Windows versions whose don't have the Ex function (XP SP3 x32, Server 2003 SP0 and earlier).
It will fix regression with Rapps startup there, due to that missing function.
CORE-17264
* [RAPPS] Display custom applications icons for installed applications
- Implement `RetrieveIcon` helper function in `CInstalledApplicationInfo` class, which retrueves the current app's icon from registry, same as it done for `CAvailableApplicationInfo`.
- Use it for loading the icon in `CAppsListView::AddInstalledApplication` function, via `ExtractIconW`. Load default Rapps icon only when the app has no its custom icon.
- Retrieve `DisplayIcon` value from registry in `CInstalledApps::Enum` function, same as other registry values (like app name, description, etc).Store it in `szDisplayIcon` string, which is used in `CInstalledApplicationInfo::RetrieveIcon` for retrieving the data of that value.
- Increase `LISTVIEW_ICON_SIZE` macro from 24 to 32, so 32x32 icon size is now used instead of 24x24. This makes displayed icons more accurate, since most of apps contain 32x32 icon, so they look a bit distorted with 24x24 size.
* [RAPPS] separate application-view from gui.cpp
