can't update

I recently tried to update Calibre 0.9.11 to 0.9.29 and after I downloaded the update file and tries to run it I got a message stating "This installation package could not be opened. Contact the application vendor to verify that this is a valid Windows Installer package." I still have the file but can't open it. Can you help?
