Working offline is no longer supported in AccountRight PC Edtion. If you work offline, you should put your company file online to keep working. This ensures your data is protected with automatic online backups, and you get live bank feeds, multiuser access, and the latest updates.
If you've created a company file, upgraded a company file or previously opened one, the file name should appear in the Welcome window's Recently opened company files list when you open AccountRight.
But if you've been invited to access an online company file or you can't see the file there, here’s how you can open and sign in.
Open a company file
Start AccountRight. The Welcome window appears.
Click Open a Company File. The Library Browser appears.
Select the file you want to open.
Click Sign in. If you haven’t signed into your MYOB account yet, you will need to enter your account's email address and password (the same details you use to sign into the My Account website).
Complete the sign-in in your default browser. When you sign in to an online company file, AccountRight will open the MYOB sign-in page in your default web browser. Enter your email and password as you normally would. Once signed in, click Open MYOB AccountRight. Your company file will open in AccountRight desktop.
You don't need to sign into AccountRight browser separately when you're already signed into the AccountRight desktop app (and vice versa). Once you’re signed in, you’ll stay connected across platforms without needing to re-enter your details (unless your software times out after inactivity).
More about single sign-on
If you need to switch to AccountRight browser, you won’t need to sign in again. You can also open your online files in a web browser at app.myob.comSimultaneous logins across multiple files are only supported when using the same user ID.
If a user (for example, an Online file user) needs to be able to have multiple company files open at the same time, they'll need to have been invited to each of those files with the same MYOB login details (email address and password) for each file.
If prompted, enter your two-factor authentication code. This is part of two-factor authentication to protect your online data. All company files you own, or have been invited to access will be listed in the Library Browser window.
Opening network or offline files
With the end of offline support for AccountRight PC Edition, you need to have installed Server Edition to open a company file stored on a network or on a computer. If you're hosting a file on a network, you'll need Server Edition installed on every workstation that accesses it.
Server Edition is built on older technology that's no longer being maintained. It won't receive bug fixes, security updates or new features, and may stop working entirely. We recommend moving your files online as soon as practical.
If you use both offline and online files, you can have both PC Edition and Server Edition installed on the same computer.
Open a company file stored on another computer or network
Start AccountRight. The Welcome window appears.
Click Open a Company File. The Library Browser appears.
Locate the file you want to open. Click Network Libraries. If an AccountRight library has been set up on another computer or server on your network, you'll see the computer's details listed in the Library Browser.
If no network libraries are listed below the Network Libraries button:
Make sure the computer you want to access is running, and has the Server Edition of AccountRight installed on it.
Click Add Network Library in your Library Browser window, and enter the name (or IP address) of the computer you want to connect to.
Click OK. The network library’s name will appear in the left panel of the Library Browser.
Select the library name and all files stored in the AccountRight library of that computer will appear.
For network tips, see our Set up a network help page.
Can't find the file? See the FAQs below for help.
Double-click the file you want to open.
If the Sign in window shown below appears, enter your company file sign-in details. If you don't know these details, speak to the administrator that set you up. If you created or upgraded the file yourself, the Administrator password might be blank. If you're a new user that's just been set up by an administrator, you can click Change Password to change your password from the one assigned by your administrator.
Click OK and your file will open.
Open a company file stored on your computer (offline)
Start AccountRight. The Welcome window appears.
Click Open a Company File. The Library Browser appears.
Locate the file you want to open. Click My Library. All files that are saved in the library folder of your computer will be listed. Only files with the file extension .MYOX stored in the library folder can be opened using AccountRight. If needed, you can add company files to the AccountRight library.
Older AccountRight company files, with the file extension .MYO or .PRM will need to be upgraded to use in the new AccountRight. As AccountRight v19 and earlier has been discontinued, you'll need to get help from MYOB to upgrade any company files from this version.
Double-click the file you want to open.
If the Sign in window shown below appears, enter your company file sign-in details. If you don't know these details, speak to the administrator that set you up. If you created or upgraded the file yourself, the Administrator password might be blank. If you're a new user that's just been set up by an administrator, you can click Change Password to change your password from the one assigned by your administrator.
Click OK and your file will open.

FAQs
I can't find my offline company file - help!
If you can't find a company file stored on your computer, try this:
Simultaneously press the Windows and E keys on your keyboard (the Windows key is between the Ctrl and Alt keys).
In the left panel, click Local Disk (C:).
In the search box (in the top-right corner) type *.myox. The asterisk tells Windows you're looking for everything that ends in ".myox" (the file extension for AccountRight company files). If your company file ends with ".myo" it's an AccountRight Classic (v19) company file and will need to be upgraded.
All AccountRight company files on your Local Disk (C:) drive will be displayed. The file location will also be displayed.
Once you've found your company file, you'll need to add the company file to your AccountRight library to be able to open it.
Why am I getting the message "Company file can't be found"?
This message means the offline company file you're trying to open has been moved from your AccountRight library.
You'll need to add the company file back to your AccountRight library to be able to open it.
Can't find your company file? Try this:
Simultaneously press the Windows and E keys on your keyboard (the Windows key is between the Ctrl and Alt keys).
In the left panel, click Local Disk (C:).
In the search box (in the top-right corner) type *.myox. The asterisk tells Windows you're looking for everything that ends in ".myox" (the file extension for AccountRight company files).

All AccountRight company files on your Local Disk (C:) drive will be displayed. The file location will also be displayed.
Why am I getting the message "Unable to open company file"?
The above message 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 - they'll all be listed in the Recently opened company files list on the AccountRight Welcome window.
Make sure you're only opening company files you're entitled to access, or request that access from the company file owner.
For additional troubleshooting, see Error: "Unable to open company file".
How do I delete an AccountRight file that's on my computer?
AccountRight company files that aren't online are stored in the AccountRight library folder on your computer, or the network computer that hosts the file. If you want to permanently delete a file, you need to delete it from the library folder.
Open Windows Explorer (Windows 7) or File Explorer (Windows 10).
Go to the Documents > MYOB > My AccountRight files folder (or the folder where your library is located).
Can't find your file?
AccountRight company files have a .myox or .myo file extension. You can try searching for your file (such as YourFileName.myox) or for all files with this file extension (such as *.myox). If your file is stored on another computer (such as a file server), make sure it's switched on or not in sleep mode.
Select the file and delete it.
Can I open more than one company file at a time?
Yes! You can open multiple copies of AccountRight (by double-clicking the shortcut icon on your desktop) then open separate company files in each.
So start AccountRight then open the first company file. Then start AccountRight a second time and open the second company file.
What if my company file is in a ZIP file?
If your company file is in a ZIP (compressed) file, it's most likely a backup of an offline company file. To open it, you'll need to restore the backup. You can choose to:
open the backed up copy of your company file to view historical information (only available in AccountRight Server Edition or AccountRight PC Edition 2026.4 or earlier).
overwrite an online company file with the backed up company file (AccountRight PC Edition only). You'll lose any work done in the online file since the backup was created and you can't undo it.
