I have just "upgraded" my laptop from Vista to Windows 7. I have attempted to install Windows Live Essentials 2012. Each attempt creates an error message "An unknown error ocurred - 0x80040705. Source: dotNet40". I have disabled Windows Firewall - no difference. I have disabled my Avast Internet Security - no difference. Following an answer to a post on this forum, I have run Fixit which decided that there was no error to fix! Any suggestions please? As I mainly want Mail, any alternative email prog. you would recommend if I can't get Live Mail?
