Registry GetSubKeyNames() lists different keys than Regedit?

20

We are using WIX to install a number of services we create. I am writing a quick utility to dump the currently installed services. I just iterate over subkeys of:

SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall 

looking for DisplayName. The problem is, only two of my ten services show up in the list.

However, when I look at the subkeys in Regedit, they are there. As well, they are in the installed programs (and I can find them in SELECT * from Win32_Product too).

I looked through the MSDN docs, trying to find out if there is some special view of the registry that I am missing. Maybe it is a privilege issue? But I am running the tool as admin. Is there some hive mounting issue?

Just to be clear with the code, here is the test app code (from this answer):

String registryKey = @"SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall";
using(Microsoft.Win32.RegistryKey key = Registry.LocalMachine.OpenSubKey(registryKey))
{
  foreach(String subkeyName in key.GetSubKeyNames())
    Console.WriteLine(key.OpenSubKey(subkeyName).GetValue("DisplayName"));
}

Any thoughts on this?

• What exactly are you trying to do? Also, you should tag this as "Wix". - dvallejo
• Also, please don't repeat the tags ("C#") in the title. I'm sure you don't think that GetSubKeyNames is a C# method, but the title read that way. - John Saunders
