In the Main Menu, click Help, Update.

To update Open Dental versions, your location must be on support and have a unique registration key.

See our video: How to Update Open Dental to a New Version



Install an Update

In the Update window, click Check for Updates.

Versions: Up to three available versions will list.

Click Install next to the version you want to install.

  • Once you install and run the update, all other computers will automatically update when the program is first opened so you can easily keep all your computers updated.
  • If you update from a computer that is running a higher version of Open Dental than the database (server) it connects to, the server will also update and other workstations connected to the server will update the next time they start Open Dental.
  • Some updates will automatically backup the database as a preventive measure. Large enterprise organizations that update often and have a comprehensive backup strategy can contact Open Dental technical support to disable this process.
  • Automatic backups during the update process are generated in the MyISAM format. If you ever need to restore from an automatic backup after a failed update, offices that use InnoDB will need to repeat the DB conversion process.

Updates for Enterprise Users

Enterprise users who do not allow normal users to have administrative privileges and prefer to centrally manage all software updates can use the standard Windows solution for pushing updates. Use a Group Policy to enable per machine software assignment.

For workstations with multiple Open Dental executables to different locations: After updating via the File Copier, Open Dental will re-connect to the same database as before, rather than the last database that was opened.

Updates for Open Dental Cloud Users

Open Dental Cloud users must contact Support to schedule an appointment for updates.

Updates for Foreign (Non-U.S.) Users

Foreign releases of beta versions require additional time for bug testing, so users outside the U.S. may note a delay.


When I run Setup.exe, the first screen gives three options of Modify, Repair, and Uninstall instead of notifying me it is updating.

Click cancel and try the download again. It is just trying to reinstall the version you already have installed. You will run into issues like this if you take a copy of your database home. When you run Setup.exe on your home computer, it will try to update the program, but might not have access to the most recent download. If you switch databases (Choose Database window), it may not be able to locate the Setup.exe depending on Data Paths setup. If you install the update from a disk, you won't even use the window above.

When updating a second computer, I receive the message "The expected version information was not found in this file "\OpenDentImages\UpdateFiles\Manifest.txt. There is probably a permission issue on that folder which should be fixed."

On the first computer (where the update did work), right-click on the Open Dental icon and Run as Administrator. Click Help, Update, then click Setup in the upper left. On the Update Setup window, click Recopy. Return to the second computer and try the update again.

When updating, I receive the message "The remote server returned an error: (403) Forbidden."

Update the Website Path for Updates field to point to https://www.opendental.com/updates/

Update fails and the database becomes corrupt.

Revert back to an older version. Older version setup.exe files are usually located in the OpenDentImages\SetupFiles folder. Follow these steps.

  1. Log every workstation out of Open Dental.
  2. Stop the MySQL service.
  3. Rename the corrupted database (include the version number in the name).
  4. Locate the backup made during the update and make a copy of it. Rename the copy with the same name as the original database. If you have trouble renaming the database, you may need to pause or stop backups or antivirus software.
  5. Move the renamed database to the original database path.
  6. Restart the MySQL service.
  7. Uninstall Open Dental.
  8. Run the Open Dental setup.exe file for older version.
  9. Verify everything is working on server.
  10. Log into every workstation. The Open Dental version on the workstation should still be the 'old' version. If not, then repeat steps 7 and 8 on the workstation.

Receive a warning error during an update that you will lose data, with an option to continue or abort.

If you choose to continue and want to retrieve lost data, contact Open Dental support and request an escalation to an engineer.

Error: Update in Progress

If anyone attempts to launch Open Dental during an update, they will receive a notification that an update is in progress. Typically the user should wait a few minutes, then click Try Again. An Override button will be visible on the computer that started the update or on admin computers listed in FreeDentalConfig.xml. Click to stop the update and launch Open Dental.
