  1. I have struggled to solve this problem for nearly half a year – googling once a week for six months!!!- and finally found your post. Halleluiah!! Your post makes me dance in the office. Thx soooooooooooooooooooo much. I’ve sent you a small donation and hope it would be enough for a cup of coffee for you. – from South Korea, Claire.

    1. Claire thank you for your feedback, I am really glad this post helped you! I also find Sticky Notes irreplaceable and don’t understand why original developers decided to abandon it.
      Thank you for your donation, it will be enough for more than a cup of coffee here in Slovenia:)
      I wish you lots of dancing in the office:)

  2. THX!! This was a life saver…. I actually scrapped Evernote and switched to OneNote due to better tablet / handwriting support – but missed the StickyNotes part badly.
    So – activated Evernote again for StickyNotes use only – syncing to 2 pc’s – ove worked (key still there) – other failed!!

    Solved with your .dll file…. 🙂

    Thx for sharing this!!!

  3. Thank you so much for this! Just installed Sticky notes on my new work laptop and had a panic when I saw it was no longer supported lol

  4. Many thanks ! Searched a solution for weeks. Works perfectly now !
    I made a donation for a “cup of tea”. Good luck.

  5. Hi Simon, I have a little question.
    I want to made a shortcut as to get a new note directly with a shortcut key (ctrl + …).
    So, in the shortcut’s properties, I must have in the target line something as : “C:\Program Files (x86)\Evernote Sticky Notes\StickyNotes.Wpf.exe” / …… ?? , but what may I have just after / for adding a new note with Sticky Note ?

    For example with Outlook note I may have this target for a new note : “C:\Program Files (x86)\Microsoft Office\Office12\OUTLOOK.EXE” /c ipm.stickynote

    By advance, many thanks

    1. Hi Richard, I would first like to thank you for your donation.

      I believe the command line argument you are looking for is /addnote

      “C:\Program Files (x86)\Evernote Sticky Notes\StickyNotes.Wpf.exe” /addnote

      There is no possibility to choose the colour of the new note, it will be yellow by default.

      If you would like to force the synchronisation, the command line argument is /syncnow

      “C:\Program Files (x86)\Evernote Sticky Notes\StickyNotes.Wpf.exe” /syncnow

      I hope this has helped you.

  6. Hi Simon,
    Searched for days!!!!
    Tried the solution and worked with international version of Evernote.
    BUT I am currently using a localized verion of Evernote (for China only, called “印象笔记“), I cannot login with my localized account.

    As far as I know, they are basically same app with different host severs. Checked with official website, I noticed the Oauth requrest url is https://www.evernote.com/oauth for internation version while https://app.yingxiang.com/oauth for Chinese version.

    Possible to repack a Chinese verions of DLL for me?
    Thanks in advance.

    1. Hello Fan LU,

      thank you for your donation.
      I will modify the dll for you in the next 48 hours and send the modified version to your email.

  7. Many many thanks!
    I have been using Evernote Sticky Notes for three years now and got used to it pretty much, so when I encountered this problem I was pretty upset.
    I am not a rather skilled computer user, to say the least, but the way you explained it seems perfect.
    And it works!
    Thanks a lot!

    1. Hello Dennis,

      I’m glad this is working for you, thank you very much for your donation and your feedback.

  8. I looked a whole night for a solution and you finally offered it!!
    Thank you very much that’s great and so easy to do, just to change the old .dll with your new file.
    Again thanks a lot

  9. Avesome!! Appreciate, many thanks for your solution, my small donation is on the way 🙂 Cheers, Wladimir, Germany

  10. Oh no, help me PLAEEEEEESE.
    i just still couldn’t get the authentification
    “An error occurred – please try again. ”
    I don’t understand at all
    i do it all step by step
    what should i do?

  11. Not working for me unfortunately, although getting a different message:

    “Could not load file or assembly ‘StickyNotes.OAuth, Version-1.5.9.0, Culture=nautral, PlublicKeyToken=null’ or one of its dependencies. The module was expected to contain an assembly manifest.

    Can you maybe help me with this?

    1. Hello, please try re-installing the Sticky Notes software (make sure you have version 1.5.9 installed) and then follow instructions on how to replace the dll file. Restart your computer afterwards.

      1. Thanks for your reply.

        I have tried all possible scenarios without any luck unfortunately.

        Using Win 8.1

  12. Simon.

    You Sir, are amazing!
    I was so bummed when my Evernote StickNotes stopped syncing, and even more so when I read that the original devs had just let it pass.
    I kept it on my PC in hopes that somebody would take up the gauntlet and fix it.
    That someone is/was you.

    From the bottom of my heart, THANK YOU!

    (I am flat broke at the moment, but when I have a couple extra dollars to spare, I will gift a few your way.).

    😀 Happy Day!!! 🙂

    1. Jason you are welcome and thank you for the wonderful comment, it really brightened my day.

  13. I can’t say anything new that people before me didn’t say. Anyhow, thank you for great work.

  14. I don’t know how much a cup of coffee is worth where you are, but I sent 5 euro. Being able to move my notes to my windows 10 laptop is worth it. 🙂

  15. WOW!!!!!!! Thanks so much man from Brazil, you’ve saved me!!!!!!!!!!! 🙂 🙂 🙂

    1. Hello Leandro,

      it hasn’t stopped working, everything works as intended.

      If you describe your issues in more detail, I may be able to help you.

  16. Yesterday stickynotes stopped working. I was looking for fix, found out authors are not maintaining it long time and luckily found this page. I started to decompile this library myself but I gave it a try to google for it first and found your post 🙂 saved my time!

    for those who are afraid of installing new DLL -> difference in source code seems to be just in changing POST method to GET method (nothing else) – Simon please correct me if I missed something.

    Best! and thanks!

    1. Hi HuffYk,

      yes you are right, nothing else was changed.

      I’m glad I have saved you some time.

      Best Regards,
      Simon

  17. Thanks mate, left you a tip for the effort you made and helped us all out with!
    This saves and increases my productivity at least 10 fold if not more!

  18. Wow – just downloaded and installed per your instructions. Was getting the “Length” error when I tried to get a authorization link as well. Of course, your fix was excellent and now it’s working nicely. Easy to follow instructions. Thank you so much.

  19. Mate – double thumbs up!!!

    All worked fine for me. Well done! Thanks for making a great programme work again.

  20. Thank you so much. I am now able to use the program again. I have made a small donation — enjoy the coffee!

  21. Thanks for this great solution. The software’s website is down, by the way. I fear it may be gone.

    1. Hello Daniele,

      their Evernote Sticky Notes presentation page at http://stickynotes.edo-soft.com/ has been down for quite a while, but the authentication page at http://hosting.edo-soft.com/ is still up and running. The expiration date for edo-soft.com domain is 2018-07-08 according to whois.com. If developers decide to not renew the registration before that date, I will offer them my web server to host their API in order for the Evernote Sticky Notes to remain operational.

      If you were referring to issues with the evernote.com servers – Evernote is conducting brief weekly maintenance every Wednesday at 6PM PT. If you experience any issues with Evernote Sticky Notes, you can check the status of the Evernote service at http://status.evernote.com/

      Best Regards,
      Simon

      1. Thanks, it’s a great relief to know you’ll step in as API host in case of problems. I use this app a lot, very simple and quite useful for my workflow.

        1. You are welcome. Hosting this API wouldn’t put much stress on the server, since every Evernote Sticky Notes user only needs to visit it once per year – during the re-authorisation process. Judging by current blog visit statistics that means around 20 – 30 users per day.

    2. Hello,

      I would like to inform you that I have reverse engineered the Evernote Sticky Notes authorization procedure and wrote a script that reads and displays the authentication token provided by the Evernote server.
      I have uploaded the script on my server, which means we no longer have to depend on the edo-soft.com server for finalizing the authorization procedure.

      You can download the updated oauth library from the blog post:

  22. oh lord, thanks for the help really appreciated it!!
    I have been facing this trouble for quite a long time and finally it resolved!
    Thanks bruh 🙂

    Regards,
    Calvin

  23. Thank you sooooooooooo much… You have saved our lives!!
    My Donation have done with love!

  24. This has saved many, many hours of my life. Thank you so much. I can’t believe Evernote hasn’t released an official sticky note app. Please get a Bitcoin Cash donation address: I want to send you money!

    1. You are welcome Steve, I’m glad to hear it.

      Thank you for your feedback and the idea about Bitcoin cash donations.

      Per your suggestion, I have created a Bitcoin Cash Wallet, the wallet address is below:

  25. Merci beaucoup, thanks a million Simon! I was soooooo sad I could not use the sync feature for months, and now it’s back thanks to your great work!
    Enjoy a good cup of coffee 😉
    Greg

  26. Thank you very much, Simon — this saved me a lot of frustration. Great example of community-mindedness!

  27. amazing!! thank you so much! you made my day and my life easier again! cheers from new zealand

  28. Hello! There appears to be a problem. I pasted the dll and requested an activation link which did give me the evernote “authorization” page and sticky is authorized again, however I get an error every time
    “This site can’t be reached
    hosting.edo-soft.com took too long to respond.”

    I think the authentication page has gone down too, even though we’re not in July yet 🙁

    1. Hello,

      thank you for informing me of this issue. I hope this is just a temporary problem with their server.

      I will contact developers of the Sticky Notes and ask them if they would be willing to transfer the API to my server, if they have decided to take it down or cancel the domain.

    1. Hello,

      yes there is currently an issue with the activation status because the edo-soft domain is down. I’m searching for a workaround. Please check back soon.

  30. Hi there Simon,

    I have just tried to replace the file and I did receive the authorisation link, but I’m receiving an error that it can’t receive from the server (400) . I went through the process exactly as described but only at the end did I see your update from May 2018. Where can I access the revised file from (your?) server?

  31. Hi there, I’ve just been through the process described above but am now getting a ‘bad server request’ error (400). I did the process before I saw your note about the 2018 changes. Could you please let me know how I can download your replacement script (from your? server).

    Cheers
    Janine

    1. Hello Janine,

      the file that is available on the blog is the newest library file available (that is from May 2018). I have just checked and the authorization process works without any issues for me.

      You should download the newest .dll file from the blog and replace the file which is inside the Evernote Sticky Notes folder. While you do this, Evernote Sticky Notes app should be closed (don’t forget to check the taskbar, if the icon is there, you should close the app).

      If this still doesn’t work for you, it would be great if you could provide the screenshot of the error you are getting.

      Best Regards,
      Simon

  32. Hey Simon,

    Just wanted to give you another big THANK YOU for getting this working for us all again!
    It’s an absolute wonder that Evernote doesn’t see the value in producing such an application themselves! For me and many others, I would imagine, Evernote Sticky Notes is indispensable.

    Anyhow, thanks again and please keep up the good work.

    Take care and have a great year! 😀

    1. Hi Jason,

      You are welcome and thank you for your feedback:)

      I agree with you – Evernote should develop its own app – judging by more than 3000 downloads from my blog within the past year, there seems to be quite an interest in this app.

      Best Regards,
      Simon

  33. Thank you so much for this post.

    Save me for tons of problems.

    Have an excellent day.

  34. I tried it today, request activation link was successful, also verification code I got, but after pasting verification code and hitting button Complete activation it returns error:

    Sticky Notes
    Error
    The remote server returned an error: (400) Bad Request.

    or error
    Unauthorized…

    In other way – all in your guide is ok, but this is maybe new problem, exist any solution?
    Thank you.
    Miro

  35. Ok now!

    I created mix of updated script and authorization DLL.
    used your StickyNotes.OAuth.dll (updated version works not)
    and updated StickyNotes.Core.dll (updated version works)
    and after link request and finishing activation Sticky Notes working correctly.

    Miro

  36. Hi Miro,

    Are you able to provide the changes you made, I have the same issue with being able to get the authorization code from Evernote but it is not accepted in StickyNotes – this is after updating DLL etc

    Rory

    1. Hi Rory,

      can you provide some screenshots or the error message you are getting?

      I have checked the Evernote Sticky Notes after reading the comment from Miro, but there were no issues with the authorization process.

      I have clean installed Sticky Notes v1.5.9 and replaced the .dll file as per instructions in the post.

    1. You are welcome and thank you very much for sharing this on Evernote Forum – it seems that your action has already helped at least one user (Zigzagmolly) 🙂

  37. You have saved my sanity! I NEED Evernote Sticky Notes to survive work and family. Please never stop!! You have made this 63 yr old Grandmother/Medical Informatics Nurse so very happy! Thank you!

    1. Hello Zigzagmolly,

      you are very welcome and thank you for your kind feedback.

      I don’t intend to stop supporting the Evernote Sticky Notes – I see that quite a large number of users is depending on it daily (myself included).

  38. Hello Simon,
    On 17/07/2017 I managed to revive my Sticky Notes based on your instructions.
    Some two weeks ago, after a Windows Update my Sticky notes stopped synchronizing.
    I tried to repeat the same procedure that I did last year but it does not work.
    When I request activation link nothing happens. Just nothing happens and that’s it.
    I tried to reload my PC but nothing helps.
    Is there anything I missed?

  39. Hello Simon,
    It seems the very mention of your name makes wonders to Sticky Notes.
    As soon as I wrote the previous message to you, I tries again and everything worked.
    The Sticky Notes seems to just got scared that I turned to you for help. 🙂
    Thank you!
    Dennis

    1. Hi Dennis,

      thank you for the kind feedback – the latest .dll file should work without any issues, but sometimes there are momentary issues with servers, so it could take a few tries.

      I’m glad to hear it is now working for you.

      Best Regards,
      Simon
