If the key is not one of the predefined registry keys, call the RegCloseKey function after you have finished using the handle. If lpSubKey is a pointer to an empty string and hKey is HKEY_CLASSES_ROOT, phkResult receives the same hKey handle passed into the function. As an example of an error related to WOW6432Node, consider the defect in a program system consisting of 32-bit and 64-bit units that interact with each other and use different register more info here Jun 12, 2011 at 4:00pm UTC modoran (2060) Following code works for me, it is in VS documentation: 1

You RARELY need to change stuff in the registry yourself. The lpSubKey parameter can be a pointer to an empty string. I am sure of not passing any "INVALID PARAMETERS" and the keys are "PRESENT". The problem is the part that tries to open the registry path again to read the entry names.

In contrast, the RegSetValueEx function specifically requires that the key be opened with the KEY_SET_VALUE access right. For more information, see Registry Virtualization and 32-bit and 64-bit Application Data in the Registry.

And RegSetValueEx() returns same value. You might often encounter such errors in various 32-bit register management utilities like, for instance, here.

This behavior causes issues when 32-bit applications try to access the WOW6432Node node using of Windows API functions (for instance, RegOpenKeyEx and RegEnumKeyEx). How could a language that uses a single word extremely often sustain itself?
