System.ArgumentException = while deleting registry key

[Asawari]

Hi

I'm trying to delete 1 registry key. It is giving me exception as
System.ArgumentException: Cannot delete a subkey tree because the
subkey does not exist.

For deleting subkey, how to provide the key name?

For e.g.

1) "SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall" + "\\" +
subKeyName

Here "subKeyName" implies the software that is to be deleted.

OR

2) only subKeyName

OR

3)
"HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Uninstall"
+ "\\" + subKeyName

Any help / clue will be very much helpful.
Thanks in advance.

Regards
Asawari

I guess - you want to delete 1 key & you are using "DeleteSubKeyTree"
Try using "DeleteSubKey" instead

No.
i'm using DeleteSubKey method only.

Inspite of using this method, it's giving this exception.

If the key does not have further keys under it (in left pane)
Registry.LocalMachine.DeleteSubKey(@"SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\Blah");

Use DeleteSubKeyTree, if it has further keys under it (as in
sub-folders)
