I'm having the same problem with Win7 64bit. I've even tried removing all signs of Evernote (deleting c:\Program Files (x86)\Evernote folder) then cleaning up the registry, rebooting and then trying a fresh install and still get the same result. I even resorted to contacting Evernote support last week but have heard nothing back! Seems like an installer issue with respect to the latest windows update? Bit frustrating because I've come to rely on Evernote for work notes, silly me for relying on free software.
