File I/O And Registry :: Listing Multiple Regkeys Under Multiple Keys?

I am trying to list all printers (PrintersConnections) under all users (HKEY_USERS)

problem is I dont know the user name keys in advance and need to exclude .DEFAULT and *_CLASSES so first I need to list all key names (%usernamekey%) directly under HKEY_USERS then for all keys that lists lsit all keys under HKEY_USERS\%usernamekey%PrintersConnections

Here is the code I have so far but I get errors about object variable not set, I suspect because of the way I doing the for each and listing the key names and then doing it again

Code:
Private Sub DetectPrntrs()
Try
Dim RemReg As Microsoft.Win32.RegistryKey

[Code].....
