There are two versions of the "Unable to open company file" error, but the text in each error message is different. This helps identify which error you're getting and how to fix it.

Take a look at the examples below to find your error and its solution.


"The company file is not registered to the AccountRight Live account that you are currently logged in to."


This error means you're signed in to your MYOB account but you don't have access to the file you're trying to open. This can happen if multiple company files have been opened on the same computer and the files are listed in the Recently opened company files list on the AccountRight Welcome window.

If you try to open one of these files but you're not entitled to do so, the error will display. So make sure you're only opening company files you're entitled to access, or request that access from the company file owner so they can add you as a user.


"Unable to perform this action"


This error occurs if you're trying to open an AccountRight 2020.2 company file in an older AccountRight version.

To open the file, you'll need to install the latest AccountRight version.


"The connection to the server was lost. Please check that the server is on and connected to the network."


If you're getting this error using AccountRight 2020.1 or later, see AccountRight server service issues for additional troubleshooting.

If you're using AccountRight 2019.1, the port we're using has been seen to conflict with other manufacturers' ports. We recommend changing the port on your server to fix the error. Follow the steps below to use port 56668.

  1. Exit AccountRight.
  2. Download CONNECTION-HOTFIX-2019.1.ZIP.
  3. Extract the contents of the zip file to a folder on your desktop.
  4. Double-click the regkeys_2019.1.reg file.
  5. Click Yes.
  6. Extract the file Huxley.Application.exe.config to the applicable location based on your Windows version.

    • 32-bit Windows: extract the file to C:\Program Files\MYOB\AccountRight\2019.1\SE

    • 64-bit Windows: extract the file to C:\Program Files (x86)\MYOB\AccountRight\2019.1\SE
  7. Restart the server/host machine.
  8. If the error persists, see AccountRight server service issues for additional troubleshooting.
