Seems the issue is the failure to uninstall previous version. Windows add/remove did not unistall it either. I had to download Revo Uninstaller to fully uninstall all registry entries, left over files, etc.
Same here with Evernote_22.214.171.12436.exe. Failed with automatic update and with manual installation on 64-bit Win7 OS. The good news is that it didn't trash my 126.96.36.19996 installation. Given that so many people use EverNote as part of their daily lives, this is disturbing.
