We've been unable to login to MYOB Accountright SE desktop since this morning.

After clicking login on desktop app - redirected to browser to login - click yes to open desktop app - nothing happens, the desktop app doesn't open.

We've tried the following but nothing worked:

Clearing browser cache
Using different browser (Edge/Chrome)
Reinstalling MYOB Accountright SE
Clearing the MYOB cache itself under %localappdata%

Our installed version is the latest 2026.400.10013 (or 2026.4.1.13) which should be the most recent one.

Please advise.

Please try the following:

HKEY_CURRENT_USER\Software\Classes\myob-arl to myob-arl.old

Problem was that MYOB version number wasn't updating in this particular key in HKCU.

Don't change the one in HKLM or HKCR.

This will work for AccountRight SE, have used it across multiple customers today with success.

Absolutely agree with KinaB. I have been waiting since 11 June for a response to my ticket and I'm still waiting.

Please escalate this to your devs immediately. This is a farce.

It took over a week to get a reply to my ticket - they sent through a script which appears to be useless at this stage. I suspect it's due to the MYOB update.

I am once again applying the same HKCU fix, for the same users I did this for previously.

MYOB cannot leave this like this. Customers cannot access their accounts and whilst you offer a desktop/server version as well as a browser one, you are expected to support it.

This is particularly critical for customers who use third-party software alongside MYOB - they cannot use the MYOB online service alone.

When is MYOB going to do something about fixing this SSO problem??

@AmandaMYOB this regedit workaround needs to be used again on the latest 2026.5 update otherwise SSO doesn't work. Please fix this.

Baycoast

Where do you suggest we try HKEY_ CURRENT etc? and what do you mean by "Don't change the one in HKLM or HKCR?

I've been unable to log in since 11 June and I am still waiting for assistance.

Hi Mattvee, we also had issues with logging in again yesterday after the auto-update to 2026.4.1.14 - this time you could see that the sign in worked, but MYOB Accountright app was so laggy that you couldn't even open a file.

What worked for us this time was a clean reinstall of MYOB - uninstall, delete the MYOB folder under %localappdata% & the myob-arl folder under Registry Editor for good measure (as all the files are online anyway) - then downloading and reinstalling MYOB. Worked like a charm.

Mattvee

I also have this login issue on a couple of PC's in our office.

Have tried everything mentioned so far including the HKCU change which is "marked as solution", but no luck.

We are using 2026.4.1.14 and the problem only started yesterday for us.

Outstanding.

Worked.

Gratitude.

same here, wasted days trying and sending multiple requests for assistance to no avail. Still have not received assistance from myob support

Lyn your correct it only works when the incorrect versions are displayed.

lynn561237

Hi @KinaB and @AmandaMYOB thank you for the suggestions, they worked for all of our affected users. The MYOB version number was showing as the old 2026.400.10009 for some reason.

vinpal

Hi Amanda,

FYI your solution does not work.

My team has been troubleshooting the problem and know what the issue is.

This cannot be resolved by the end user, your software has an issue. Please advise your dev team.

Hi @AmandaMYOB, we tried renaming the file as suggested in your link for that particular staff and it's now working. Thank you very much for your reference.

mlim

the problem for us is that we have a server version and it works for most of us except for one staff who can't seems to login after trying everything

AmandaMYOB

Hey @lynn561237 @Jlee @mlim

Other members have reported the same problem and have found a solution to work, you can check it out here. Hope this helps.

mlim

same here. wasting a day and a half trying to login and still got nowhere. why can't MYOB leave the system alone when it is working perfectly

Jlee

I am having the same problem. What is the solution?
