Hello everybody! I want to install Office 2003 Pro on Windows Vista home Premium and it does not work. Autorun mode, a message says "this operation requires elevation". If I explore and setup, the, setup told me that the file is missing E2561404.CAB What do I do now throwing my computer. I have also tried to install this on a new system. Genuine activation failed on my both computer for Office 2007 and office 2003.
