After upgrading to Windows 10, my Windows Live Mail stopped working saying that the program can't start because MSVCR110.dll is missing from my computer. According to advice found here, I uninstalled Windows Live Essentials...then I attempted to reinstall Windows Essentials 2012- then I got a error message "Windows Essentials could not be installed. code 0x780070643.  I need to get this working... or, at least, import the current mail into another program. What must I do?
