title: COM unregister/register type library problem
body: <p>I have a .NET COM DLL that I want to unregister. I do:
  regasm.exe /u ConfigManager.dll</p>
  
  <p>When I look with COM-ole viewer app I still see in type libraries section an entry for ConfigManager( specifies the path to ConfigManager.tlb there). How can I make sure I deregister for good any entries of ConfigManager.dll COM ?</p>
  
  <p>I ask this because I have a nasty error where it seems that ConfigManager clients do not see some types from ConfigManager and want to make sure I deregister and register again ConfigManager </p>
