 TRIOS Module Missing or Not Working in Unite?

  • Scanning applications are missing after an update
  • No scanning step appears when creating a case

Before You Start

A little context helps narrow down the fix faster. Before troubleshooting, it's helpful to know:

  • Is this happening on one workstation or several?
  • Did it start right after a software update?
  • Are all TRIOS-related features missing, or just specific ones?
  • Are you signed in with the correct 3Shape account?
  • Do you know if the correct licenses are assigned to your account?
  • Does this affect every case, or only certain ones?
  • Is your scanner detected by your computer?
  • Have you recently switched to a new computer or 3Shape account?
How to Fix It

1. Check for Software Updates

  • Open the Unite Store.
  • Check for pending updates.
  • Install all available Unite and TRIOS updates.
  • Restart Unite once updates finish.
  • Confirm the TRIOS Module now appears.

2. Confirm the TRIOS Module Is Installed

  • Open the Unite Store.
  • Locate the TRIOS Module.
  • If it isn't installed, install it now.
  • Restart Unite after installation.

3. Verify Your Licensing

  • Confirm you're signed into the correct 3Shape account.
  • Verify your account has the appropriate licenses assigned.
  • Make sure the account belongs to your company (watch out for duplicate accounts under the same company).
  • Confirm your scanner license is active.

4. Check Your Account Configuration

If the issue started after signing in, transferring ownership, or changing accounts:

  • Confirm you're using the correct account.
  • Verify the account contains your scanner licenses.
  • Remove any incorrect accounts, if needed.
  • Sign in again using the account tied to your licenses.
  • Check whether the module now appears.

5. Run a Repair Installation

If the TRIOS Module shows as installed but still won't work:

  • Close Unite completely.
  • Stop all 3Shape services.
  • Run a Repair Installation.
  • Restart your computer.
  • Launch Unite again and check functionality.

6. Test Your Scanner and Workflow

Once the module is back, confirm everything is working correctly:

  • Create a new test case.
  • Verify "Scan Only" appears.
  • Confirm scanning workflows load correctly.
  • Test the Analyze and Send functions.
  • Confirm your scanner connects.
  • Run a test scan.

7. Plugin or Module Errors

If you see "Error registering plugin TRIOS" or a similar message:

  • Confirm all updates are installed.
  • Run a Repair Installation.
  • Confirm your computer meets minimum requirements.
  • Check that your graphics card (GPU) is detected.
  • Make sure your graphics drivers are up to date.
  • Reinstall the module if the issue continues.

8. Check Your Hardware and Environment

  • Confirm a supported GPU is detected.
  • Update your graphics drivers.
  • Confirm required Windows services are running.
  • Check that security/antivirus software isn't blocking the module.
  • Confirm your computer meets the minimum TRIOS requirements.
Common Causes
  • Incomplete Unite updates
  • A corrupted TRIOS Module installation
  • A module that failed to deploy during an update
  • A missing TRIOS Module after a software repair
  • Signing in with the wrong 3Shape account
  • Licenses assigned to a different account
  • Scanner licenses not being detected
  • Corrupted module files
  • Graphics driver issues
  • Unsupported hardware
Quick Checklist
  • Install the missing TRIOS Module from the Unite Store
  • Complete all pending Unite updates
  • Run a Repair Installation
  • Restart Unite after updates
  • Verify licensing and account assignment
  • Sign in with the correct licensed account
  • Reinstall the TRIOS Module if needed
  • Update graphics drivers
  • Confirm your workstation meets requirements
  • Restart 3Shape services

Tip: Most TRIOS Module issues come down to an incomplete update, the wrong account being signed in, missing licenses, or a module that didn't finish installing after an upgrade. Checking these first will resolve the majority of cases.
