This is not a question, meant more like a forum posting. FYI, in case it happens to you.
Evernote 184.108.40.20613 for Windows, check for updates, did not find newer version online, required manual download to update. My conditions are Evernote 220.127.116.1113 under Windows Vista Home Premium 64-bit SP2. I found newer version Evernote 18.104.22.168 available, manually downloaded and installed. Update/upgrade install required uninstalling the installed older version before install of the newer version.
(I have been using the built in update check successfully to get updates. This time Check for update reported "You already have the latest version". I did scan with Software Informer which reported newer version. I expected it was incorrect as in most cases, no newer version that applies to my setup or actually test version. But this time Software informer got it right and helped me in a case where the software's own update check did not work.)
