What happened

This error has several possible causes:

  • You tried to open an application in an earlier release of HCL Notes® than the one in which the application was created; for example, the application was created in Notes version 6 or later, but you are using Notes version 5.
  • The application you tried to open may have a corrupted application icon on your workspace.
  • You tried to open a document that is corrupted.

What you can do

Do one of the following:

  • If you have access to a later release of Notes, open the application in it. If not, ask the application manager or person who sent you the application to click File > Application > New Copy and create a copy for you that has an .NS5 or .NS4 extension, depending on what release of Notes you are using.
    Note: To make a new copy, click View > Advanced Menus.
  • Remove the application's icon from your workspace, exit and restart Notes, to re-add the application, open it again.
  • Notify the application manager about the document you cannot open.
