I've successfully used Revo Uninstaller Pro v3.0.2 to uninstall the rogue Evernote version 4.6.3 on two Win 7 Pro 64-bit notebook PC. The keys are: 1. Start up Revo, use "Forced Unintall", select "Advanced scanning mode". 2. At "Program's exact name:", enter "evernote". 3. Select everything in the registry to delete (see attached jpg). 4. Apply step 1-3 again if Evernote still shows up in Revo. 5. Install the latest version 188.8.131.5236(268644) public. 6. Enter your Username and Password. 7. Re sync again to download all the notebooks from server. I've tried to add/remove notes and the new Evernote version runs as expected. I hope this could help everyone.
