Same issue here using W8 *64. Seems similar issue here: http://discussion.evernote.com/topic/35243-evernote-for-windows-463-rc/page-3 And this: http://discussion.evernote.com/topic/35673-installation-problem-with-v463/page-2#entry194897
Same problem, the installer crashes and does not install. This has happened on both W8 *64 PC's I use. The installers were auto update, and manual download from your site. Work around for me was to use Revo uninstaller to remove the leftovers of the programme from failed upgrade/install, after that it installed ok.
