For Glenwood Dental Group, I can't open CTs because OnDemand 3D can't find the license. In the rest of the OPs the error message disappears after a few attempts.

**OnDemand3DApp Error dialog box** is displayed on screen with the message: **"Cannot find your license for this application."** The dialog title reads **"OnDemand3DApp Error"** and contains a red X error icon. An **OK** button is present to dismiss the dialog.

is the software installed on the server? is there a DB? is it running? Have you restarted it?

Checking if is installed on the server, I can reach the db. It works on any other op, I restarted the server.

it is installed on the pan pc which is the server. Willi Master is pointing to the server, if you try to to open an x ray on demand pops up on any other op besides this one.

i am not sure how this works. is this anything new or they use it for some time yet? Maybe worth calling the vendor

# Fix OnDemand 3D license error on single workstation

## Problem
OnDemand 3D displays "Cannot find your license for this application" error on one specific workstation when attempting to open CT images. The error appears consistently on this workstation but works normally on all other operatory computers. The software is installed on the panoramic PC (server), database is accessible, and Willi Master is properly configured to point to the server.

## Resolution
1. Verify OnDemand 3D software installation on the affected workstation
2. Confirm network connectivity between the workstation and the server hosting OnDemand 3D
3. Check that the workstation can properly communicate with the OnDemand 3D database
4. Restart the OnDemand 3D service on the server if not already done
5. If the issue persists after these steps, contact the OnDemand 3D vendor for license-specific troubleshooting

The error may indicate a workstation-specific licensing or communication issue that requires vendor assistance to resolve.
