Windows Installer is not accessible

Like AuntDi1947, I get an error message indicating that Windows Installer is not accessible, but I tried to install a new update for Calibre e-book management.  That's happened? I did that for a while now without a problem. Why is she suddenly disappeared?  How can I get the installer works again without an installer to reinstall?  I use Vista 32 SP2. Please help me.  Thank you.
