Registry.LocalMachine.OpenSubKey() returns null

Question

I get a null back from this attempt to access the Windows Registry:

using (RegistryKey registry = Registry.LocalMachine.OpenSubKey(keyPath))

keyPath is SOFTWARE\\TestKey

The key is in the registry, so I do not know why it's not finding it under Local Machine hive.

in your comment to Dana you said you gave the asp.net account access, however did you verify that that is the account that the site in running under? Impersonate and the anonymous access user can be easy to overlook.
