  Im trying to write code to delete a subkey (including all values stored under it), see snippet below:

  .....
  Dim rKey as RegistryKey

  
  rKey = Registry.Classes_Root
  rKey = rKey.OpenSubKey("CLSID",true)
  rKey.DeleteSubKey("{227FE4FD-9D11-4DA1-A1C0-3F0BB9AF21EC}")
  ...

  
  But when I run this it raises the following:

  'System.UnauthorizedAccessException' occurred in mscorlib.dll
  "Cannot write to the registry key"

  Any ideas what I'm doing wrong, would be most grateful.

  Thanks.....

  1. You are not logged on as an administrator

  2. You are trying to delete a key without the necessary permissions, try adding the <System.Security.Permissions.RegistryPermissions({param}) attribute at either class or method level.
