Can you give examples of the specific keys you are attempting to write? Vista and Win7 created the concept of protected registry nodes that are "owned" by Windows and they don't let others mess with them, but for back compat they swallow the related errors so it only causes silent failures. That sounds like what is happening in your case, but having the actual keys involved will help determine that for certain. -- Bryan

The code is written in C# and uses Registry.LocalMachine.CreateSubKey(). I added some logging that tells me that the return value is not null and the custom action does not throw an exception. But the key is never created. What is really weird is that various functions are called that use OpenSubKey(). These functions also log correct return values and do not throw exceptions. But the key is never created. The custom action works fine in XP but fails in Windows 7. I am running the custom action with Impersonate="no".
